Iflight Blitz H743 Wing Relay 2 (GPIO 81) not working #27421

Open qazico opened 3 weeks ago

qazico commented 3 weeks ago

Relay 2 does not turn off 9v pin on flight controller.

Assigned CH8 to relay 2. Verified relay 2 is associated to GPIO pin 81. Tried different relay default options with no change. iFlight H743 Wing hwdef includes Blitz H743Pro hwdef. H743 Wing includes 2 camera inputs (H743 Pro only has one camera input). Suspect 2 separate GPIO required on H743 Wing (one for camera switch one for 9v vsw)

Probably related with (Matek H743): https://github.com/ArduPilot/ardupilot/issues/27357

Also check some voltage switch jumpers/bridges. Probably you need to switch/solder it if your board has them

Only jumpers I see are for the servo voltage jumper pads. This fc is a bit different than the matek offerings.
