About the ESP32 BUCK WLED NO BOARD

ESP32 BUCK WLED NO BOARD is an open source ESP32 PCB design by lepetidozo, published on GitHub. It is a 4-layer board measuring 55.9 × 78.7 mm, with 37 components from 23 distinct parts.

Its main chip is the ESP32-WROOM-32E, from the ESP32 family. Other key parts include the LM2596T-ADJ, AMS1117-3.3 and 74AHCT125. By type, the board carries 11 capacitors, 10 resistors, 4 ICs, 4 connectors, 2 transistors and 2 switches.

It belongs with the power & battery designs in this gallery.

From the project

I wanted to make a custom WLED controller for my bedroom's ledstrip and to learn more about electronics and PCB design

ESP32 BUCK WLED NO BOARD: common questions

What microcontroller does the ESP32 BUCK WLED NO BOARD use?

The ESP32 BUCK WLED NO BOARD is built around the ESP32-WROOM-32E, from the ESP32 family.

How big is the ESP32 BUCK WLED NO BOARD?

The ESP32 BUCK WLED NO BOARD measures 55.9 × 78.7 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the ESP32 BUCK WLED NO BOARD?

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

Where can I download the ESP32 BUCK WLED NO BOARD design files?

From the lepetidozo/wledController_V1 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ESP32 BUCK WLED NO BOARD design in my own project?

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

Can I test firmware for the ESP32 BUCK WLED NO BOARD 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.
