The 12v sw is a nice feature as it saves me from needing a relay. The only odd thing is it seems the PIO is inverted for me: give it digital high or PWM and the 12vsw pad loses power, give it digital low or minimum PWM and the 12vsw is powered. Could be a skill issue on my end. I didn't manage to get the PIO to cooperate with a servo tested but it worked fine with an ESP32 using digital and using PWM. ## Features - This FCHUB-12S is designed specificaly for X Quad. supports 8~60V DC (3~12S LiPo) input, 5V 5A and 12V 4A regulators, high precision up to 440A current sensor range, suit for 4/5 inch Carbon Fiber FPV Racing Quad Quadcopter Frame - Matek has stepped up their game with this FCHUB-12S, support up to 12s lipo battery. - 4x70A cont, 4x110A burst. 4x ESC power /signal/ telemetry pads.
