Duet 3 Mini 5+ connecting 5V Fan

[chuser]

Hello

I have a Mini 5+ and would like to connect a 5V fan. Is there a way to do this without StepDown? Or can I feed 5V via V_OUTLC2?

What would be the best solution?

why not use the out6 5v PWM connection for lasers etc?

But essentially, you can take a 5v feed from somewhere on the board and feed it into ground of one of the fan connectors as the mosfets switch the negative side.

Thanks for your answer

A good idea. I need 2x 5V fan and 1x 12V fan and want to have the cleanest solution.

The out6 5V PWM somehow does not work. This one always has 5V present. And I would need 2 such connections.

Can I connect the 5V_EXT with V_OUTLC2 to have 5V on OUT1 and OUT2?

Yes that should work. Just be very careful on connecting the jumper wire to prevent connecting VIN and 5v.
