Lil-Cheat: common questions
What microcontroller does the Lil-Cheat use?
The Lil-Cheat is built around the ATmega32U2-AU, from the AVR/Arduino family.
How big is the Lil-Cheat PCB?
The Lil-Cheat measures 298.5 × 76.2 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Lil-Cheat?
125 components, from 12 distinct parts. The full bill of materials is listed on this page.
Where can I download the Lil-Cheat design files?
From the kiiings/KIIIN01 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Lil-Cheat design in my own project?
The repository has no license, so all rights stay with kiiings. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Lil-Cheat 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.
