WLED ESP32 Controller: common questions

What microcontroller does the WLED ESP32 Controller use?

The WLED ESP32 Controller is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the WLED ESP32 Controller PCB?

The WLED ESP32 Controller measures 62.2 × 30.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the WLED ESP32 Controller?

22 components, from 14 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 WLED ESP32 Controller design files?

From the Hasenpups/WLED_ESP32_Controller 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 WLED ESP32 Controller design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the WLED ESP32 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.
