ESP32 battery management module: common questions

What microcontroller does the ESP32 battery management module use?

The ESP32 battery management module is built around the ESP32-WROOM, from the ESP32 family.

How big is the ESP32 battery management module?

The ESP32 battery management module measures 173.5 × 192.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the ESP32 battery management module?

828 components, from 47 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 battery management module design files?

From the KomplexKapharnaum/KXKM_ESP32_Audio_Battery_hardware 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 battery management module design in my own project?

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

Can I test firmware for the ESP32 battery management module 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.
