Balancing cam panel: common questions

What microcontroller does the Balancing cam panel use?

The Balancing cam panel is built around the ESP32-S3-MINI-1, from the ESP32 family.

How big is the Balancing cam panel PCB?

The Balancing cam panel measures 100 × 100 mm, has 4 copper layers and is 1.565 mm thick.

How many components are on the Balancing cam panel?

116 components, from 40 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 Balancing cam panel design files?

From the NEOgHacking/Balancing_cam repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Balancing cam panel design in my own project?

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

Can I test firmware for the Balancing cam panel 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.
