Badge-2025: common questions

What microcontroller does the Badge-2025 use?

The Badge-2025 is built around the ESP32-C3, from the ESP32 family.

How big is the Badge-2025 PCB?

The Badge-2025 measures 8.8 × 11.7 mm, has 2 copper layers and is 0.24 mm thick.

How many components are on the Badge-2025?

105 components, from 26 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 Badge-2025 design files?

From the endsummercamp/badge-2025 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 Badge-2025 design in my own project?

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

Can I test firmware for the Badge-2025 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.
