Hi bluuu,
a few questions regarding the LED connections, do they support 12V LEDs with 50mA?
Which of the two pads is plus, and which one is minus? Am I correct when I assume that minus is the one near the edge of the board.
On the M4 extension board, I have for UART 5V-Rx-Tx-GND, on the OSD board mention RST-Rx-Tx-GND, the last three pins is clear, but for the first one RST, what is this? Is it needed?
