    Here are the pads that you have to bridge to put this board into DFU bootloader mode – in case something goes wrong flashing new firmware and you happen to brick it. Bridging these pads will enable you to upload new firmware. unbridge them to use the board again.

    Do M3 nylon screws fit into the mounting holes fairly well? I’ve been looking for a 20×20 flight controller with OSD and M3 mounting holes (and 4-in-1 ESC micro connector is good too).

      Yes, it has M3 mounting holes

    For how much amps is the 5V out rated? I want to power the tx03 AIO cam directly from the board.
    Thank you

    • dmitry

      It is rated 1Amp and you should be able to power tx03 without issues, but one thing to keep in mind that Pololu 1A is far more superior than built-in BECs
