WLED-Controller: common questions

What microcontroller does the WLED-Controller use?

The WLED-Controller is built around the esp32-wemos-d1-mini, from the ESP32 family.

How big is the WLED-Controller PCB?

The WLED-Controller measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the WLED-Controller?

63 components, from 27 distinct parts. The full bill of materials is listed on this page.

Where can I download the WLED-Controller design files?

From the LostInCompilation/WLED-Controller-PCB repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the WLED-Controller design in my own project?

The repository has no license, so all rights stay with LostInCompilation. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the WLED-Controller 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.
