About the ESPFanController PCB

ESPFanController 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 36.5 × 56 mm, with 23 components from 16 distinct parts.

Its main chip is the ESP32-WROOM-32, from the ESP32 family. Other key parts include the AMS1117-3.3. By type, the board carries 9 resistors, 4 capacitors, 3 modules, 2 ICs, 2 connectors and 2 diodes.

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

From the project

Control and monitor up to three PWM fans with an ESP32

Controller for up to three 5V or 12V PWM-Fans with an ESP32 at it's core

The included yaml file is my config for ESP-Home but of course this can also be programmed in any compatible language you like...

ESPFanController: common questions

What microcontroller does the ESPFanController use?

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

How big is the ESPFanController PCB?

The ESPFanController measures 36.5 × 56 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESPFanController?

23 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESPFanController design files?

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

Can I use the ESPFanController 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 ESPFanController 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.
