Badge: common questions
What microcontroller does the Badge use?
The Badge is built around the XIAO-ESP32-C3-DIP, from the ESP32 family.
How big is the Badge PCB?
The Badge measures 58 × 37.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Badge?
27 components, from 4 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 design files?
From the Pegoku/fallout-badge 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 design in my own project?
The repository has no license, so all rights stay with Pegoku. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Badge 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.
