Mod12003: common questions

What microcontroller does the Mod12003 use?

The Mod12003 is built around the ATXMEGA32E5-M4U, from the AVR/Arduino family.

How big is the Mod12003 PCB?

The Mod12003 measures 90 × 90 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mod12003?

230 components, from 63 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mod12003 design files?

From the semianalog/mod12003 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Mod12003 design in my own project?

Yes, under the terms of its CC0-1.0 license, which semianalog chose for the repository.

Can I test firmware for the Mod12003 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.
