 Note that `PICO_BOARD`, `USB_VID` and `USB_PID` are optional. If not provided, `pico` board and VID/PID `FEFF:FCFD` will be used.
+For Waveshare RP2350-One board, add `-DWAVESHARE_RP2350_ONE=ON` to enable RGB LED support on GPIO 16.
 
 Additionally, you can pass the `VIDPID=value` parameter to build the firmware with a known VID/PID. The supported values are:

 ## Driver
 
 Pico FIDO uses the `HID` driver, which is present in all operating systems. It should be detected by all OS and browser/applications just like normal USB FIDO keys.
