ESP32-li ion cell monitor pan: common questions

What microcontroller does the ESP32-li ion cell monitor pan use?

The ESP32-li ion cell monitor pan is built around the ESP-WROOM-32, from the ESP32 family.

How big is the ESP32-li ion cell monitor pan PCB?

The ESP32-li ion cell monitor pan measures 94 × 26 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32-li ion cell monitor pan?

47 components, from 17 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 ESP32-li ion cell monitor pan design files?

From the fabriziotappero/esp32-embed repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the ESP32-li ion cell monitor pan design in my own project?

Yes, under the terms of its GPL-3.0 license, which fabriziotappero chose for the repository.

Can I test firmware for the ESP32-li ion cell monitor pan 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.
