Controller mb atu: common questions

What microcontroller does the Controller mb atu use?

The Controller mb atu is built around the ATmega32M1-AU, from the AVR/Arduino family.

How big is the Controller mb atu PCB?

The Controller mb atu measures 115 × 69.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Controller mb atu?

56 components, from 37 distinct parts. The full bill of materials is listed on this page.

Where can I download the Controller mb atu design files?

From the c3h9dx/controller_mb_atu repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Controller mb atu design in my own project?

The repository has no license, so all rights stay with c3h9dx. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Controller mb atu 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.
