README

This repository contains the design and production files that I used to build by own ESP32-based OpenTherm* and ON/OFF thermostats.
The devices is based on a ESP32-S3 microcontroller, and can include exclusively a OpenTherm driver circuit or a latching on/off relay to drive the boiler. Optionally, a BME280 sensor can be soldered onto the board in order to measure temperature, humidity and pressure (and use them for control).

PCB Design
Final Result (OpenTherm version, no BME280)
Mounted by me by hand, imperfect but functioning.

Questions
How big is the Board clima esp32 PCB?
It measures 77.7 × 64.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Board clima esp32 use?
63 parts, built around the ESP32-S3-WROOM-1-N4, BME280, AMS1117-3.3 and SM4007PL. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Board clima esp32 KiCad files?
From the edofullin/esp32-devboard-clima repository on GitHub, at the commit this page was made from: the board is board-clima-esp32.kicad_pcb and its schematic board-clima-esp32.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Board clima esp32 design in my own project?
Its repository states no licence, so its author keeps all rights: ask edofullin before reusing the design.

The ESP32-S3 uses 3.3V. I want onboard indicator LEDs, and the option to have offboard LEDs as well. Using addressable WS2812-type LEDs is flexible. These need a 5V supply.
