Avrcraft m644: common questions

What microcontroller does the Avrcraft m644 use?

The Avrcraft m644 is built around the ATMEGA1284P-A, from the AVR/Arduino family.

How big is the Avrcraft m644 PCB?

The Avrcraft m644 measures 85.1 × 49.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Avrcraft m644?

49 components, from 34 distinct parts. The full bill of materials is listed on this page.

Where can I download the Avrcraft m644 design files?

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

Can I use the Avrcraft m644 design in my own project?

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

Can I test firmware for the Avrcraft m644 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.
