It is possible by creating timer irq handler and toggling BL pin manually. This is sub optimal but do not require any H/W changes. |

I came across this note in the code.
I don't know what it's meant, because I don't know the design of other transmitters.
Does this mean that the firmware can't handle dimming, or is it that there is only a switching transistor on the PCB.
If we could output PWM to the (BL) MCU pin, then we could connect an external device that can do it.
According to the picture, only R19 would be removed on the PCB. The output from the module is connected to the LED pads 1 and 2. We also have Vbat + BL + GND for the module.
What do you think about it?
