Overview
ESP32LedDriverV2 is an open-source printed circuit board by AdamCLarsen, from the AdamCLarsen/Esp32LedDriver repository on GitHub, published under the MIT licence. It is a 4-layer board of 100 × 57 mm with 60 parts on 42 nets, routed with 375 tracks and 39 vias.
It is built around the ESP32-WROOM-32, R-78C5.0-1.0 and TC4420CPA, with the AMS1117-3.3 among its other parts. Its parts include 12 ICs, 10 capacitors, 8 resistors, 8 transistors and 3 diodes. It belongs with the home automation and IoT boards and the ESP32 boards of this library.

README
README.mdEsp32 LED Driver
An ESP32 LED Driver for use with ESPHome. Supports 12 volt and 24 volt LEDs.
NOTE:
This was a fun project I did for myself, where I added a few minor things I wanted, and maybe you will learn something from what I put together. However after I finished by baord, I found QuinLED, I recommend you go look at QuinLED-An-Deca over having my board manufactured.
Goals
- Work with 24 Volt LEDs, at least 1.5 amps
- Independed control of two RGB-W strips, or eight white LED Strips
- Work well with Home Assistant
- Built in power monitoring
- Price is $50 to $75 per board
Pin assignment on ESP32
- Test LED - ~IO19 (was ~IO13 in V1)
- SDA - IO21
- SCL - IO22
- INA219 - i2c address - 45
- CHAN 1 - IO32
- CHAN 2 - IO33
- CHAN 3 - IO25
- CHAN 4 - IO26
- CHAN 5 - IO27
- CHAN 6 - IO18
- CHAN 7 - IO17
- CHAN 8 - IO16
The result
Case
I have designed a case for it as well over on OnShape for use with a 3D printer.
Print uses M3 3D Printing Brass Nuts, 5mm x 6mm Embedment. Found them on Amazon here.
Other resources
- WLED Software that also runs on ESP32 and should work on this board using the Analog controls, if you don't have HA or don't use ESPHome.
- QuinLED-An-Deca Use this board over my board.

Questions
How big is the ESP32LedDriverV2 PCB?
It measures 100 × 57 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ESP32LedDriverV2 use?
60 parts, built around the ESP32-WROOM-32, R-78C5.0-1.0, TC4420CPA and AMS1117-3.3. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ESP32LedDriverV2 KiCad files?
From the AdamCLarsen/Esp32LedDriver repository on GitHub, at the commit this page was made from: the board is KiCad-Project/ESP32/ESP32LedDriverV2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32LedDriverV2 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
