MM-control: common questions

What microcontroller does the MM-control use?

The MM-control is built around the ATMEGA32U4, from the AVR/Arduino family.

How big is the MM-control PCB?

The MM-control measures 106 × 45 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the MM-control?

161 components, from 43 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the MM-control design files?

From the sl1pkn07/Prusa repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the MM-control design in my own project?

The repository has no license, so all rights stay with sl1pkn07. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the MM-control without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
