About the Garage door controller PCB

Garage door controller is an open source ESP32 PCB design by latonita, published on GitHub under the MIT license. It is a 2-layer board measuring 100 × 100 mm, with 125 components from 46 distinct parts.

Its main chip is the ESP32-WROOM-32E(4MB), from the ESP32 family. Other key parts include the EL3H7(B)(TA)-G, XL1509-5.0E1, AMS1117-3.3, DRV8701PRGET and SN74HCS08DR. By type, the board carries 55 resistors, 25 capacitors, 11 transistors, 10 ICs, 7 diodes and 4 crystals.

It belongs with the robotics & motion designs in this gallery.

From the project

Garage door controller with integrated motor driver 24V/36V, 7A

Features: - DRV8701 driver - selectable mosfet gate drive - and overcurrent protection - PowerSO mosfets - shall be enough to run 24V/7A and more - External interface for common RF-receivers - RX-480R / RF11A04 - HCS301 based - Fabrication - Prepared for automated assembly on JLCPCB - Most of components are basic, no unnesessary Pick-and-place feeding fees. I personally order only couple of Extended parts to be soldered.

Garage door controller: common questions

What microcontroller does the Garage door controller use?

The Garage door controller is built around the ESP32-WROOM-32E(4MB), from the ESP32 family.

How big is the Garage door controller PCB?

The Garage door controller measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Garage door controller?

125 components, from 46 distinct parts. The full bill of materials is listed on this page.

Where can I download the Garage door controller design files?

From the latonita/garage-door-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 Garage door controller design in my own project?

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

Can I test firmware for the Garage door 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.
