What are the pins for the Sonix board that plug into the FC? Would it be possible to use the board on another Pix based quad to do video and record other logs on another card?
Check Kevin’s diagram here for TX/RX. See also this and this for flight board.
Definitely possible to connect to another flight controller and have the Sonix board act as a companion computer. In fact there was some discussion about this in last dev call , and talk of a possibly upcoming wiki on how to do it.
yep, it should work fine, just make sure you set the flight board to use 625000 baud on the uart. That is the rate the sonix firmware expects. We could make that a parameter on the sonix board if needed.
