First of all, thanks for making a smart stepper motor controller! I’ve been hoping for something just like this from Pololu for years (really)!
I just started playing with one and it’s great. I want to bump up the current limit, and I was wondering if the plated pad on the opposite side of the board from the TI chip is intended as a heat sink pad, or if the sink needs to be directly mounted to the chip on the under-side of the board. I am planning on running this in excess of 2 A per phase.
I’m really excited to try pairing a few of these with the Maestro script-able servo controllers. I wonder if that same kind of self-executing script functionality could be baked into future Tic versions?
