Open source schematics for ratgdo PCB

Credit and inspiration for this work goes to @rlowens to let me know that there are other technical folks out there who needed this other than myself.

The basic PCB schematic shown here in the Readme does not describe any circuitry other than the serial line garage door control and obstruction sensor. All other optional features provided by ratgdo can be reverse engineered as needed, or may already be solved by one of the schematics the community has uploaded!

RatGDO-OpenSource-D1Mini-ESP32: common questions

What microcontroller does the RatGDO-OpenSource-D1Mini-ESP32 use?

The RatGDO-OpenSource-D1Mini-ESP32 is built around the mini_esp32, from the ESP32 family.

How big is the RatGDO-OpenSource-D1Mini-ESP32 PCB?

The RatGDO-OpenSource-D1Mini-ESP32 measures 51.8 × 63.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RatGDO-OpenSource-D1Mini-ESP32?

12 components, from 8 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the RatGDO-OpenSource-D1Mini-ESP32 design files?

From the Kaldek/rat-ratgdo repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the RatGDO-OpenSource-D1Mini-ESP32 design in my own project?

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

Can I test firmware for the RatGDO-OpenSource-D1Mini-ESP32 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.
