About the Controller PCB

Controller is an open source ESP32 PCB design by robhaswell, published on GitHub. It is a 2-layer board measuring 43.3 × 67.5 mm, with 18 components from 6 distinct parts.

Its main chip is the ESP32_DevKit_V1_DOIT, from the ESP32 family. Other key parts include the SN74HCT245PWR. By type, the board carries 11 connectors, 4 capacitors and 3 ICs.

A 10-channel RGB controller based on the ESP32 microcontroller

Important: I have successfully ordered and assembled this project, but since then I altered the 47uF capacitor package so that it is not an extended part at JLCPCB. The author accepts NO RESPONSIBILITY for this product working, and it has not undergone extensive safety testing. Use at your own risk.

Controller: common questions

What microcontroller does the Controller use?

The Controller is built around the ESP32_DevKit_V1_DOIT, from the ESP32 family.

How big is the Controller PCB?

The Controller measures 43.3 × 67.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Controller?

18 components, from 6 distinct parts. The full bill of materials is listed on this page.

Where can I download the Controller design files?

From the robhaswell/RGB-controller repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Controller design in my own project?

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

Can I test firmware for the 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.
