Slim style: common questions

What microcontroller does the Slim style use?

The Slim style is built around the ATMEGA32U4, from the AVR/Arduino family.

How big is the Slim style PCB?

The Slim style measures 386 × 101.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Slim style?

194 components, from 18 distinct parts. The full bill of materials is listed on this page.

Where can I download the Slim style design files?

From the Neil-de-grass-eating-Bisson/Canvas-Mahjong-Keyboards repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Slim style design in my own project?

The repository has no license, so all rights stay with Neil-de-grass-eating-Bisson. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Slim style 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.
