I’m using OpenMV N6 with PIR board (which uses P7, P8 for PWM control of LEDs).

Also attaching the Driver board for 4 independent outputs. (The driver board typically uses P7, P8 for PWM, but I don’t need that)

I have very few PCB skills. Am I missing a built-in option to disable PWM on the driver board, or do I need to find a way to tie those pins high? (Or low?)

Thank you,

Qwideman

Hi, you just de-solder the blobs here to disable the LEDs:

And on the driver board here:

So, you just desolder the ones you don’t want connected.

I DO want to use the LEDs on the PIR board, using the PWM signal on P7, P8 from the camera.

Can I set the Driver Board so that it will work without a PWM signal, or will it need a signal of (PWM = 100%) in order to drive the outputs as binary outputs?

Sorry about a newbie question: If I desolder the blobs for P7, P8, on the driver board, can you confirm that will disconnect P7, P8 and set it to work without any PWM signal?

Yes, desolder the blobs.
