Badge: common questions

What microcontroller does the Badge use?

The Badge is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the Badge PCB?

The Badge measures 100 × 61 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Badge?

27 components, from 8 distinct parts. The full bill of materials is listed on this page.

Where can I download the Badge design files?

From the AnakinDmaker/badge_pcb repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Badge design in my own project?

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

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.
