Atom47: common questions

What microcontroller does the Atom47 use?

The Atom47 is built around the ATMEGA32U2-AU, from the AVR/Arduino family.

How big is the Atom47 PCB?

The Atom47 measures 242.2 × 72.1 mm, has 2 copper layers and is 1.2 mm thick.

How many components are on the Atom47?

139 components, from 30 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 Atom47 design files?

From the IndianBoy42/keyboard-pcbs repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Atom47 design in my own project?

The repository has no license, so all rights stay with IndianBoy42. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Atom47 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.
