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.

Nsec badge-2025-panel: common questions

What microcontroller does the Nsec badge-2025-panel use?

The Nsec badge-2025-panel is built around the C2934560, from the ESP32 family.

How big is the Nsec badge-2025-panel PCB?

The Nsec badge-2025-panel measures 197 × 249.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Nsec badge-2025-panel?

80 components, from 27 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 Nsec badge-2025-panel design files?

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

Can I use the Nsec badge-2025-panel design in my own project?

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

Can I test firmware for the Nsec badge-2025-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.
