About the Esp led dimmer PCB

Esp led dimmer is an open source ESP8266 PCB design by julianschuler, published on GitHub under the MIT license. It is a 2-layer board measuring 22.5 × 33.5 mm, with 14 components from 13 distinct parts.

Its main chip is the ESP-01, from the ESP8266 family. Other key parts include the TPS5430DDA. By type, the board carries 4 connectors, 3 capacitors, 2 transistors, 2 resistors, 1 IC and 1 diode.

It belongs with the iot & wireless designs in this gallery.

From the project

An wireless dimmer for monochromatic LED strips based on the ESP-01

This repository contains the PCB files for a wireless dimmer for up to two monochromatic LED strips based on the ESP-01. It can e.g. be integrated into Home Assistant using ESPHome.

The dimmer is powered via a DC barrel jack and supports both 12V and 24V LED strips. The LED strips are connected via screw terminals.

It is designed to make use of the PCBA services of JLCPCB and uses as many basic parts as possible. You can use the awesome KiCAD JLCPCB tools for exporting the corresponding fabrication files. Excluding the ESP-01 module, the cost per assembled PCB is around 5€.

Esp led dimmer: common questions

What microcontroller does the Esp led dimmer use?

The Esp led dimmer is built around the ESP-01, from the ESP8266 family.

How big is the Esp led dimmer PCB?

The Esp led dimmer measures 22.5 × 33.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp led dimmer?

14 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the Esp led dimmer design files?

From the julianschuler/esp-led-dimmer repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Esp led dimmer design in my own project?

Yes, under the terms of its MIT license, which julianschuler chose for the repository.

Can I test firmware for the Esp led dimmer without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
