I haven't needed to mess with it.

Daniel Green -

Hi, thanks for a great tutorial!

Does the firmware of the QQ-S need to be updated/replaced as well, or will these drivers run with stock FW?

Thanks again!

RJ T - crwdns2934203:0crwdne2934203:0

You can either, flip the orientation of the plug on the board, or modify config values in the firmware config file and re-flash the firmware. I chose to flip the plug so I would need to mess with flashing firmware.

Do you need to reverse the plug for a 2209? Difference between 2208 and 2209 for my QQS Pro?
