CFX power switch not working...voltage is 2.5
« on: June 06, 2021, 05:25:54 AM »
Hey, does anyone know why my power switch isn't working all of a sudden...I did a voltage check and it's at 2.5. The aux switch is still at 3.3

Try removing the switch and check again. Test also the 2 3.3v regulated to ensure the board has proper power

Detached the entire board, tested the regualated pads, they are both 3.3V. Aux switch is still at 3.3V and still works, but power switch is at 2.5V...when I try to connect power nothing happens and the accelerometer starts to get hot. I think there might be a tiny bit of solder in it...
