MultiWii

hi i have one of the above boards, recently i took out the mag so that i can use an external mag (cut the trace for voltage and one of the i2c channels)


(not my photo)

it is like the one in the above image (below the ABC led) but both are red. may i know what this is about? it wasn't on before and now i'm kinda worried. what do the lights mean?

would appreciate any help, thank you!

What do the Sensor values look like in MultiWii Config?
The LED may be just showing what control mode is being used or which sensors are active.
Try find which pin on the ATmega these LEDs are connected to and then where in the code this LED is lit.

the values look normal. the leds aren't usually lit, only A B and C are usually lit. can't seem to figure out what these leds do
