2.2 EVK setup procedure
Use the following procedure to evaluate JODY-W2 series modules:
1. By default, internal antennas are selected for any transmission and reception using pig-tail
coaxial cables, as shown in
Figure 18 . To use external antennas, connect the cables to another
pair of U.FL adapters and then connect the external dual-band antennas to the SMA connectors.
2. Connect the SDIO adapter to the connector on the board.
3. Connect the evaluation board to the host system through the supplied micro or full-size SDIO
adapter card. The evaluation board uses zero insertion force (ZIF) connectors and flat cables to
connect the adapters. To connect the cable, gently flip up the small locking flap of the connector,
align and insert the cable with the blue marking pointing upwards, and then close the locking flap.
4. Check the LEDs. They correspond to different input voltage levels and turn green when the
appropriate levels are reached. At this point, the module should be detected by the host system.
5. For evaluation of the Bluetooth features, use either an SDIO interface (with flat cable shared with
Wi-Fi) or UART (with Type-C USB cable). See also
Bluetooth UART interface and Bootstrapping .
6. Install the necessary driver software for JODY-W2 series modules, as described in the system
integration manual
[2] .
2.3 Host interface for Wi-Fi (1.8 V UHS)
The SDIO interface is the only available option for Wi-Fi communication. Follow the procedure outlined
below to connect the SDIO interface for Wi-Fi:
1. Connect the micro SDIO adapter card with the micro SDIO connector J204 to the board using the
flat ribbon cable. Make sure that the blue strip at the end of the connector faces upwards when
connecting each end of the cable.
