Overview
Ardipool is an open-source printed circuit board by golgoth31, from the golgoth31/domopool repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 205.7 × 137.2 mm with 21 parts on 132 nets, routed with 60 tracks and 0 vias.
It is built around the ESP32-DEVKITC-VE, DS18B20 and ADS1115IDGS, with the DS3231MZ+, TXS0108EPW and BC557 among its other parts. Its parts include 12 connectors, 6 ICs, 2 resistors and 1 transistor. It belongs with the ESP32 boards of this library.

Funtionalities
- Read/write configuration from preferences (nvs storage)
- Mesure water temperature, ambiant temperature and water pressure
- Auto-detect DS18B20 (temperature sensors)
- Avaluate filtering time based on day hour and water temperature
- Get/Set values through grpc request
- Set time with ntp
- Send data with mqtt
- alarms on temperatures and pressure
- frost protection
- low/high pressure protection
Configuration
To ease configuration update 2 front-end are under developement:
- CLI: https://github.com/golgoth31/domopool-cli
- UI: https://github.com/golgoth31/domopool-cli/tree/master/web

Questions
How big is the Ardipool PCB?
It measures 205.7 × 137.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ardipool use?
21 parts, built around the ESP32-DEVKITC-VE, DS18B20, ADS1115IDGS and DS3231MZ+. 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 Ardipool KiCad files?
From the golgoth31/domopool repository on GitHub, at the commit this page was made from: the board is wiring/ardipool/ardipool.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ardipool design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
