Just sharing the fact that the HTCC-AB02A does have a usable green led on GPIO13
#define LED GPIO13
I spotted the factory firmware did light it up yet its not documented anywhere other than on the cirtuit diagram, its is very bright and I don’t think this pin supports PWM (that said the factory code had it very low).
Anyway, we have an LED to use.
Can HELTEC share the factory default code for this board??
