ColorCorrecter: common questions
What microcontroller does the ColorCorrecter use?
The ColorCorrecter is built around the ESP32-C3-WROOM-02, from the ESP32 family.
How big is the ColorCorrecter PCB?
The ColorCorrecter measures 20 × 77 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the ColorCorrecter?
35 components, from 24 distinct parts. The full bill of materials is listed on this page.
Where can I download the ColorCorrecter design files?
From the fujiy/Home repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the ColorCorrecter design in my own project?
The repository has no license, so all rights stay with fujiy. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the ColorCorrecter 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.
