Introduction

The IEEE 802.11a,b,g,n OEM Modules from u-blox has been developed for integration in industrial devices. The modules are providing state of the art low power features, compatibility, robustness, and reliability. The modules minimizes the work needed to implement IEEE 802.11 in a device as it provides, together with the driver package, all software, hardware, type approval, EMC certification etc. It is developed for reliable, high demanding industrial devices and applications and delivers high performance. The u-blox wireless LAN modules are available in different versions (see Product variants).

The wireless LAN modules are complete IEEE 802.11 implementations. The IEEE 802.11 modules has small form factors and the interface layout is the same as the Bluetooth and IEEE 802.15.4 modules from u-blox, which enables customers to prepare their device for both wireless LAN, IEEE 802.15.4, and Bluetooth.

Electrical interface and connectors

This section describes the signals available on the module interface connectors. There are three ways of connecting:

  • Via J6, PCB solder lands on the edge of the PCB. For more information see sections 3.2 and 5.5.
    (see the figure in section 3.1.2 Secondary side connectors).

  • Via connectors J2 and J3, 20 x 2-pin 1mm pitch board-to-board (one piece part).
    The J2 and J3 connectors exist on the module only as compression pads.
    (see the figure in section 3.1.2 Secondary side connectors).
    These pads mates with the carrier board one-piece part connector.
    For more information see section 3.2 and 5.2.

Optional (OWS451 only):

  • Via J8, JST connector (see the figure in section 3.1.1 Primary side connectors).
    The connector is a 6 x 1 shrouded pin header, 1 mm pitch.
    The JST part number is SM06B-SRSS-TB and the mating part is wire connector SHR-06V-S.
    Other connector options are also available from JST.
    For more information see section J8 Connector Description.
    Note: The JST connector affects temperature range. See environmental characteristics for details.

Pin numbering

Primary side connectors

J8 is the JST connector located on the primary side of the module. A1 is the internal antenna.
J4 and J5 are U.FL connectors for external antennas. J4 is the primary antenna connector and J5 the auxiliary antenna connector.

Secondary side connectors

J2 and J3 is the u-blox board-to-board one piece part connector. The pin layout of the connector is compatible with all OEM Serial Port Adapters from u-blox. J6 designates the solder land connector.

The solder lands of connector (J6) have a new layout compared to cB-OWSPA311g.

Electrical characteristics

The cB-0941 family is designed to be fully interchangeable with the u-blox Bluetooth product range. If the host product has space for the board, it is possible to choose freely between Bluetooth modules, e.g. cB-OEMSPA311i/x or cB-OEMSPA331i/x, or Wireless LAN modules, e.g. OWSPA311gi/x, without any change of the host product. If you design your power supply for OWS451i/x the modules will be fully interchangeable.

SPI (OWL253)

The SPI master should use polarity falling to rising with phase sampling on rising edge, shift on falling edge. Bit order is MSB to LSB.

The SPI slave has the possibility to use both normal SPI mode, with shift and sample on rising and falling edges respectively, and an enhanced high speed mode where the shift and sample are both done on the rising edge. Since this moves the shift half a SPI cycle forward, the clock frequency can approximately be increased by a factor of two given that the signal path can handle this.

Using the high speed mode does not change the setup for the master.

In order to determine the SPI clock frequency that can be used, the signal propagation delay also need to be taken into consideration. These propagation delays has to be measured for each individual setup. The clock frequency can then be approximated according to the following formulas.

Tclk = (Tod + Tprop + Tfall) * 2
Tclk_high = Tod + Tprop + Trise

Values measured on u-blox development board cb-0940-02 with a Cheetah SPI master in room temperature can be seen in table below.

Note that the measured Fmax is very close to the limit of what is possible with respect to electrical properties and propagation delays on this particular setup and there is a significant risk for bit errors. A reasonable limit using the above formula with the Tod from the chip specification below gives Fmax as follows:

Tclk = (Tod_max + Tprop + Tfall) * 2 = (9.0 + 4.0 + 4.0) * 2 => Fmax = ~29.4 MHz
Tclk_high = Tod_max + TpropTrise = 9.5 + 4.0 + 4.0 => Fmax = ~57.1 MHz

Hardware reset

A hardware-reset input is available on J1 and J3 connectors. An external reset source must be open drain or collector. The RESET-n pin is pulled-up internally with 220 kOhm (OWL253) or 56 kOhm (OWS451).

Power control

The wireless LAN modules can be operated in several different power modes.

  • Standard IEEE802.11 power save
  • UAPSD/WMM Power Save Support

Software overview

cB-0941 (OWL253)

Wireless LAN driver for OWL253 consists of a host driver in binary format or source code, and target firmware in binary format. In the overview picture below these two software parts are represented by the yellow boxes.

owl253 software overview

The host needs to be able to hold the target firmware since targets does not have on-board non-volatile memory. At startup, and at every reset or power cycle, the host driver will download firmware binaries to target before any wireless LAN operations can begin.

OS support

Software and drivers are available for the following operating systems:

  1. Linux 2.6
  2. WinCE 6.0
  3. Embedded RTOS

Customized drivers for use in embedded systems are available upon request. Contact u-blox for more information.

cB-0941 (OWS451)

The OWS451 is a serial port adapter with an UART interface and fully embedded TCP/IP stack and driver. The module is presented as a serial port/UART to the host. Raw serial data is sent to the module, which will package the data into TCP/UDP packages and transmit via Wireless LAN.

External antennas

The external antennas are connected to the module with the on board U.FL connectors. Some antennas are connected directly to the U.FL connector and some are connected via a U.FL to SMA (cB-ACC-18 or cB-ACC-48) or U.FL to reversed polarity SMA (cB-ACC-38) adapter cable.

The sections below lists the antennas that are included in the radio type approvals of the module. For each antenna the "Approvals" field defines in what country/region the antenna is allowed to use. Definitions of the "Approvals" field are:

  • FCC - The antenna is included in the FCC test reports, and thus approved for use in countries that accept the FCC radio approvals, primarily US.
  • IC - The antenna is included in the IC (Industrie Canada) test reports, and thus approved for use in countries that accept the IC radio approvals, primarily Canada.
  • R&TTE - The antenna is included in the R&TTE test reports, and thus approved for use in countries that accept the R&TTE radio approvals, primarily the European countries.

Mounting information

Module dimensions

Tolerances:

  1. Outline dimensions +/- 0.1mm
  2. Drilled hole to outline: +/- 0.05mm

Mounting holes

There are 2 x 2.3mm mounting holes on cB-0941. The reasons for the 2.3mm holes are that the threaded M2 holes on the single and double row connectors are not aligned. The outer tangents of the 2.3mm holes align the module if the single row connectors are used and the inner if double row connectors are used (see Figure 11).
Choose the outer tangent (CC distance 27.24mm) if the module is aligned and mounted with some other technique based on M2 screws (e.g. press-fit nuts), see Figure 12.

Using the J2/J3 board-to-board connectors

The board-to-board connector should be a 1 mm pitch one-piece part connector. The recommended manufacture is Samtec with many connector options available.
Chapter 3 contains more information about the connector and the electrical interface.

Single row connectors

The single row connector SEI-120-02 can be used if only J2 is needed.
This connector has a profile height of 1.65 mm and this has to be considered if components are to be mounted on the motherboard under the OEM Serial Port Adapter board.
There are alignment pins on the bottom side of the connector.
The connector is available with M2 threaded inserts that fit the mounting holes on the board (see section Suitable One-Piece Part Connectors). You may screw the OEM Serial Port Adapter board directly into these inserts. If you want to have a tighter and more secure mounting, you may use longer screws and secure it using a nut on the backside of the motherboard.
Another way to mount the module is to use press-fit nuts on the motherboard and skip the M2 threads on the connector, see section Using Press-Fit Nuts for Mounting the Module for more information about press-fit nuts.

See Figure 10 for more information about the connector and necessary measurements on the motherboard. The large mounting holes on the motherboard are designed for press-fit nuts and could be smaller if press-fit nuts are not used. The mounting holes are aligned with the outer tangent of the 2.3mm mounting holes of the module (see section #Mounting Holes).

Host PCB layout [mm] for single row connector.

Double row ASP-118580-01 connector

This connector is a double row connector and connects both J2 and J3. It connector has a height of 3.0 mm and this has to be considered if components are to be mounted on the motherboard under the board. The connector is also available with a height of 6.0 mm and 10.0 mm (The FSI-120 serie from Samtec).
There are alignment pins on the bottom side of the connector.
The connector is available with M2 threaded inserts (ASP-118580-01) that fit the mounting holes on the board. You may screw the board directly into these inserts. If you want to have a tighter and more secure mounting you may use longer screws and secure it using a nut on the backside of the motherboard.

See figure below for more information about the connector and necessary measurements on the motherboard. The large mounting holes on the motherboard are designed for press-fit nuts and could be smaller if press-fit nuts are not used.

Using press-fit nuts for mounting the module

A press-fit nut is pressed into the PCB from the bottom side with a special press tool. M2 sized press-fit nuts are suitable for the modules (see Figure 10 and Figure 11) and are manufactured by PEM Fastening Systems (www.pemnet.com), part no KFS2-M2 (see Figure 12). Be careful with the distance between the nuts regarding alignment, see the #Mounting Holes section.

Spacer-pipes are recommended to use between the PCBs when press-fit nuts are used.

Recommended M2 screw

If a double-row connector with threaded inserts or press-fit nuts are used, then recommended for mounting of modules is a ISO 7380 M2 compatible screw. A suitable screw is the BN6404 from Bossard, www.bossard.com, with TORX T6 head cap. See figure below.

If other type of screw is used please ensure that d2 is less than 3.8 mm otherwise components near the mounting holes can be damaged.

Using the J6 PCB solder pads

Host board

The host PCB footprint should not contain any traces or vias under the module except the pads interfacing the J6 pads to avoid contact with traces/vias on the module. The host pads which are soldered to the J6 pads should reach 0.5-1.0mm under the PCB and some mm outside the module. No other pads than the J6 should be soldered to the host PCB. See section #Secondary side connectors for more info about the J6 pads.

Mounting process

We strongly recommend the modules not being soldered more than 1 time after shipping from u-blox and that the modules are mounted just before the host product is being soldered the last time. Although, u-blox devices will withstand up to two reflows to an absolute maximum temperature of 250°C.

  • The PCB in our modules is made of Isola PCL-FRP-370HR with Chemical Gold Pads.
  • The modules are produced in a lead-free process with a lead-free soldering paste.
  • It is recommended that the customers make their own electrical, climate, stress and vibration tests on the final assembled product to secure that the manufacturing process hasn't damaged or affected the module in any way.
  • The modules are delivered without labels on each module when packaged on tape-and-reel. However, if they are delivered with labels on each module, the labels should be removed before the module is processed since the labels do not withstand the heat of soldering.
  • The device recommended maximum re-flow temperature is 245°C for 10 sec.
  • The device absolute maximum re-flow temperature is 250°C for 3 sec.

Antenna issues

To ensure not to cause negative influence on the RF-performance of the unit it cannot be arbitrarily mounted. This concerns the choice of enclosure material and objects in the vicinity of the unit.

A unit with an internal surface mounted antenna cannot be mounted in a metal enclosure. This restriction also includes the use of plastic with metal flakes and metallic based paint or lacquer.

The Antenna keep out Area in the picture below marks a recommended area of 10 mm clearance around the antenna that should be kept free from metal and Cu-wiring.
If a metal enclosure is required, one of the external antenna options has to be used.

See section 3.2 for more information on the antenna options available.

Equipment classes

Depending on which frequency bands this WLAN module can operate in it is defined as either class-1 or class-2 radio equipment.
The End-product that utilise the module inherits the equipment class of the module.

  • Class-1 radio equipment can be placed on the market and put into service without restrictions.
    (article 1 of Commission Decision 2000/299/EC of April 6 2000)
  • Class-2 radio equipment is equipment for which Member States apply restrictions as indicated in Article 1(2) of the Decision, which also assigns the “Alert Sign” as “Equipment Class Identifier” for this class.  

This WLAN module is defined as class-1 radio equipment when it is restricted to operate in the following frequency band

  • WLAN, ISM band 2400 – 2483.5 MHz
  • WLAN, U-NII band-2e 5470 – 5725 MHz

If the end product allows the WLAN module to be operated in the band 5150 – 5350 MHz (WLAN channel: 36 – 64) it is defined as class-2 radio equipment and must be marked accordingly.

Class-2 radio equipment must have the "alert" sign affixed on the equipment, packaging and printed in the user instruction manual.

Radio frequency exposure

The cB-0941 wireless LAN module contains a small radio transmitter and receiver.
During communication with other wireless LAN products the cB-0941 module transmits and receives radio frequency (RF) electromagnetic fields (microwaves) in the frequency range 2412 - 2462 MHz and 5180 - 5825 MHz.
The output power of the radio transmitter is very low.
When using the cB-0941, you will be exposed to some of the transmitted RF energy. This exposure is well below the prescribed limits in all national and international RF safety standards and regulations.

Electronic equipment

Most modern electronic equipment, for example, in hospitals and cars, is shielded from RF energy. However, certain electronic equipment is not. Therefore:

This equipment emits RF energy in the ISM (Industrial, Scientific, Medical) band. Please insure that all medical devices used in proximity to this device meet appropriate susceptibility specifications for this type of RF energy.

Potentially explosive atmospheres

Turn off your electronic device before entering an area with potentially explosive atmosphere. It is rare, but your electronic device could generate sparks. Sparks in such areas could cause an explosion or fire resulting in bodily injury or even death.
Areas with a potentially explosive atmosphere are often, but not always, clearly marked. They include fuelling areas, such as petrol station, below deck on boats, fuel or chemical transfer or storage facilities, and areas where the air contains chemicals or particles, such as grain, dust, or metal powders.
