Brought to you by the Team badge of NorthSec.
The NorthSec 2023 badge is based on ESP32 microcontroller (ESP32-WROOM-32-N4) which is used to drive several periphery devices:
- WiFi interface
- BLE interface
- NeoPixel RGB LEDs
The badge is powered through a USB-C port or through an external battery that can supply between 3.7V and 6V.
If you wish to hack your badge or create a new one based on the hardware. All the information is available here.
The badge firmware is based on
ESP-IDF v5.0.1
framework. The exact commit is tracked as a submodule in esp-idf, and you
can install it with these commands:
git clone https://github.com/nsec/nsec-badge.git
cd nsec-badge/
git submodule update --init
./esp-idf/install.shThe installation procedure for your OS may differ a little, please consult the documentation website if you have any difficulties.
Once the installation is complete you can build the firmware and flash it to the badge:
source esp-idf/export.sh
cd esp32/
idf.py build flash monitorIf for some reason idf.py is not able to complete the operation, refer to the
ESP-IDF documentation.
