Pot watering controller v1: common questions

What microcontroller does the Pot watering controller v1 use?

The Pot watering controller v1 is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the Pot watering controller v1 PCB?

The Pot watering controller v1 measures 64.6 × 87.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pot watering controller v1?

38 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pot watering controller v1 design files?

From the angelnu/esphome repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Pot watering controller v1 design in my own project?

Yes, under the terms of its Apache-2.0 license, which angelnu chose for the repository.

Can I test firmware for the Pot watering controller v1 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.
