ESP32-Balancing module v2: common questions

What microcontroller does the ESP32-Balancing module v2 use?

The ESP32-Balancing module v2 is built around the ESP32-S3-DEVKITC-1-N8R8, from the ESP32 family.

How big is the ESP32-Balancing module v2?

The ESP32-Balancing module v2 measures 74.9 × 74.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32-Balancing module v2?

31 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESP32-Balancing module v2 design files?

From the louisbabeschneider/Balancing-Babebot repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ESP32-Balancing module v2 design in my own project?

The repository has no license, so all rights stay with louisbabeschneider. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the ESP32-Balancing module v2 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.
