2 Electrical Interface and Connectors This section describes the signals available on the module interface connectors. There are two ways to connect to the OWLAN211b module: • Via the 2x10-pin 2mm header connector J1 (see Picture 3). • Via the 2x20-pin 1mm pitch board-to-board (one piece part) connectors, J2 through J3. The J2 to J3 connectors on the OWLAN211b module exist on the module only as a mating PCB-layout pattern (see Picture 4). Picture 3: 2x20 2mm pinlist connector, J1.

2.4 Hardware Reset A hardware reset input is available on the J1 and J3 connectors (see section 2.1). An external reset source must be open drain or collector. The RESET pin is pulled-up internally with 56kΩ. See example in A.2.2 2.5 Power Control The CB-OWLAN211b module can be put in one of four power modes. • Active mode – no power saving is done. • Sleep mode – power saving. The module is held in low power mode and only listens and responds to beacons. • Powers save mode – Maximum power save.
3 Antennas There are 2 different antenna options available: • An internal surface mounted (SMD) antenna. • An “external antenna” should be connected to a U.FL connector. Many different “external antennas” are available. See section 4.1 for more information on antenna placement. This chapter gives an overview of the qualities of the different antenna options. 3.1 Surface Mounted Antenna (internal) The unit cannot be mounted in a metal-shielded enclosure with this antenna.
3.2 External antennas The external antennas are connected to the board through a U.FL connector. Some of the antennas are connected directly to the U.FL connector of the board and some are connected using an SMA connected through a short U.FL to SMA adapter cable. Note: Antennas with SMA connectors are not approved for use in USA or Canada due to FCC regulations. 3.2.1 Antenna Accessories Part Number cB-ACC-18 Name U.FL to SMA adapter cable Connector U.

4.3 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 6) and are manufactured by PEM Fastening Systems (www.pemnet.com), part no KFS2-M2 (see Figure 7). Be careful with the distance between the nuts regarding alignment. Figure 7: KFS2-M2 press-fit nut. Spacer-pipes are recommended to use between the PCBs when press-fit nuts are used. 4.

Please insure that all medical devices used in proximity to this device meet appropriate susceptibility specifications for this type of RF energy. 7.
Appendix A - Application Notes Usually only a subset of the available functionality is of interest to the designer. In addition, depending on the host system, the electrical interface can be designed in many ways. The designer can use the step-by-step guide in this chapter as an aid in the design process. A.1 Step-by-Step Guide Table 13: Step-by-step guide with Yes and No answers.
A.2 Design Examples A.2.1 Basic Design Basic desing example. Note: The 10uF decoupling capacitor must be positioned close to the module power supply pins. This to compensate for the current peaks during power up and reset release. SPI-SS-n SPI-MOSI CPU / MPU SPI-MISO CB-0904 SPI-CLK SPI SPI-ExInt Interrupt *RESET GPIO +3.3V 10µF Figure 8: Basic design example. Version 0.
A.2.2 Reset The RESET pin can be connected to an external reset source, see Figure 9 for a switch example. If the reset signal is connected to an output signal it must be an open drain or collector, see Figure 10. Figure 9: A reset switch. The RESET pin can be left unconnected if not used. Figure 10: Design of an open collector reset from an active high output. A.2.3 Bluetooth co-existence TBD Version 0.
A.3 Test Points The firmware outputs diagnostic messages during runtime to aid driver development and for easier troubleshooting. The messages are output as serial data, TTL-level, at test point 4. See Figure 11 for localization of test points. TP1 TP4 TP5 Figure 11: Bottom View showing the location of test points. A RS232 level shifter needs to be used if the diagnostic messages shall be logged using a PC. CB-0904 TP4 COM1: RX PC TTL → RS232 Level shifter GND: e.
