3.3.2 Host MCU Board with mikroBUS Socket via mikroBUS Interface (Host Companion Mode)

The RNWF02 Add On Board can also be used with the host MCU boards using mikroBUS sockets with the control interface. The following table shows how the pinout on the RNWF02 Add On Board mikroBUS interface corresponds to the pinout on the RNWF02PC Module.

Note: Disconnect the USB Type-C cable in the Host Companion mode.

Note:
  1. For more details on the RNWF02PC Module pins, refer to the RNWF02 Wi-Fi Module Data Sheet (DS70005544).
  2. The RNWF02 Add On Board does not support the SPI interface, which is available on the mikroBUS interface.
