From the project

Software from the NorthSec badge

Brought to you by the Team badge of NorthSec.

The NorthSec 2025 badge is loosely based on the ESP32-C3 design with an ESP32-C3 microcontroller (ESP32-C3-WROOM-02-N4) which is used to drive several periphery devices:

- Eighteen NeoPixel RGB LEDs - Five buttons - One IR 'pairing' connector - Two Shitty Add-On V1.69bis connector

The badge is powered through a USB-C port or through 3 AAA batteries.
