Esp water monitor: common questions

What microcontroller does the Esp water monitor use?

The Esp water monitor is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the Esp water monitor PCB?

The Esp water monitor measures 137.5 × 86 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp water monitor?

81 components, from 32 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 Esp water monitor design files?

From the kyleronan/Esp_water-monitor 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 Esp water monitor design in my own project?

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

Can I test firmware for the Esp water monitor 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.
