Ccboard: common questions
What microcontroller does the Ccboard use?
The Ccboard is built around the ATMEGA32U4-AU, from the AVR/Arduino family.
How big is the Ccboard PCB?
The Ccboard measures 135 × 124 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Ccboard?
177 components, from 116 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 Ccboard design files?
From the troisiemetype/ccboard repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Ccboard design in my own project?
The repository has no license, so all rights stay with troisiemetype. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Ccboard 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.
