ESP32 TOUCH LED: common questions

What microcontroller does the ESP32 TOUCH LED use?

The ESP32 TOUCH LED is built around the ESP32-WROOM-32D, from the ESP32 family.

How big is the ESP32 TOUCH LED PCB?

The ESP32 TOUCH LED measures 200 × 200 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32 TOUCH LED?

23 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESP32 TOUCH LED design files?

From the mortens-lab/ESP32_tube_vu_meter repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the ESP32 TOUCH LED design in my own project?

Yes, under the terms of its MIT license, which mortens-lab chose for the repository.

Can I test firmware for the ESP32 TOUCH LED 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.
