Why did you make it?

The design is open source. I made the controller available to save you the trouble of ordering PCB and soldering surface mount parts.

What makes it special?

The midTbot is small enough to carry in your backback. It looks cool and is fun to watch.

What do I get with the kit?

You get a PCB will all surface mount parts soldered. You also get all the through hole parts, but you must solder them in yourself. There is a growing community to help you. Help is available via the GitHub issues, a Slack community and via email. You will get a Slack invite with your order or if you message me.

What does the customer need to supply?

You need to supply an ESP32 development module and some StepStick stepper drivers. There are details on the GitHub repo.
