C3 men: common questions
What microcontroller does the C3 men use?
The C3 men is built around the NJM4580, from the ESP32 family.
How big is the C3 men PCB?
The C3 men measures 86 × 89 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the C3 men?
30 components, from 23 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 C3 men design files?
From the Tert2/KiCAD repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the C3 men design in my own project?
The repository has no license, so all rights stay with Tert2. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the C3 men without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
