About the AC-Controller PCB

AC-Controller is an open source ESP32 PCB design by Qeteshpony, published on GitHub under the BSD-2-Clause license. It is a 2-layer board measuring 66 × 67 mm, with 78 components from 38 distinct parts.

Its main chip is the ESP32-WROOM-32, from the ESP32 family. Other key parts include the TPS63000 and TP4056. By type, the board carries 34 resistors, 15 capacitors, 8 transistors, 4 ICs, 4 switches and 4 diodes.

It belongs with the iot & wireless, displays & leds and power & battery designs in this gallery.

From the project

Universal WiFi-Based remote control for IoT Devices

Simple controller for IoT devices with ESP-Home and Home Assistant in mind. This project was mainly started to get better control for our AC system but I guess it can be adapted for about anything.

The system is based on an ESP32 module, a small LCD and two rotary encoders with optional support for charging and using a LiPo battery.

The hardware was designed for production by JLCPCB and as many parts as possible were selected from their basic parts library to keep costs low.

The KiCad project lives in the Qeteshpony/AC-Controller repository on GitHub; these links point at the commit this page was built from.

AC-Controller: common questions

What microcontroller does the AC-Controller use?

The AC-Controller is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the AC-Controller PCB?

The AC-Controller measures 66 × 67 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the AC-Controller?

78 components, from 38 distinct parts. The full bill of materials is listed on this page.

Where can I download the AC-Controller design files?

From the Qeteshpony/AC-Controller repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the AC-Controller design in my own project?

Yes, under the terms of its BSD-2-Clause license, which Qeteshpony chose for the repository.

Can I test firmware for the AC-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.
