4.1.2 Host Companion Mode

Figure 4-3. RNWF02 Connection for 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 RNWF02 Module.
Note:
  • To operate RNWF02 Add On Board in Host Companion mode, ensure to place the jumper cap on J201.2, J201.3, as illustrated in the above image.
  • Do not use Type-C USB cable in Host Companion mode.
