OK, here's the scenario:

We want to do some software testing using a minimalist FRC controller plus an electronics board with some switches, potentiometers and LEDS.

The switches will go to digital inputs

The potentiometers will use the analog inputs

So far, all easy to do

But the LEDS, I would like to drive from the Relay outputs on the controller directly, using the FWD and REV outputs to drive two separate LEDs e.g. green for FWD and red for REV.

Normally the Relay outputs go to a SPIKE, but I would really like to do away with them to make the test rig setup smaller and less expensive.

Is it possible to drive LEDs directly from the Relay FWD / REV outputs ?

Is there any good technical reference that explains the FRC Controller's Relay output signal drive characteristics, i.e. voltage and max current source/sink per output channel ?

Thanks in advance
