Hello friends!

I've been away a lot of time and now I'm resuming my C172 assembly...

In the past I was connecting an Uno on the Mega thru TX/RX cables but looks like now is different...

I'm not able to understand the current pic about slaves...

Someone could help me pls about these connections? Need to use 2 Unos (servo and stepper) with the Mega.

tks a lot

For stepper board use Rx/Tx port #1 on the master board:

For servo board - Rx/Tx #2:

Don't forget to upload the latest servo and stepper firmware and use latest plugin.
