      How to Connect the External Rx to Toothpick F405 20A AIO FC V4

      The new AIO board has integrated the Plug & Play Port for the external Rx, and there will be a 4-Pin connector for Rx in the package. Thus, we highly recommend pilots to use pin-connect to save the solder work. In addition, please notice that when you connect the different external Rx, the pads near the pin need to be soldered in a different way. Please solder it as the following diagram.
