. PPM receiver welded to the UART2 GND, + 5V, RX2 .Then set Receiver mode to RX_PPM in Cleanflight configurator. Notice: Before applying power, pay attention to the battery voltage selection. The default setting is 1S (4.2V); if you use 2s lipo, please first need to disconnect pin2 and pin 3 and then solder pin 1 and pin2. Prohibit the same three pads shorted together.
