LED driver: common questions
What microcontroller does the LED driver use?
The LED driver is built around the ESP32-C3-MINI-1-N4, from the ESP32 family.
How big is the LED driver PCB?
The LED driver measures 90 × 30 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the LED driver?
42 components, from 26 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 LED driver design files?
From the CodedSakura/electronics repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the LED driver design in my own project?
The repository has no license, so all rights stay with CodedSakura. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the LED driver 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.
