NorthSec 2016 Badge

nRF51 and STM32 OLED/BLE badge

NorthSec's public 2016 badge repository documents an electronic attendee badge with nRF51822 and STM32F072CB microcontrollers, OLED display, BLE, battery management, touch buttons, red/green LEDs, USB, SWD programming, and STM32 USB DFU support.

Why It Mattered

It anchors NorthSec's public hardware-badge lineage in a dual-MCU design that blended BLE attendee interaction, OLED output, USB development, and firmware-release practices before the later ESP32 badge era.

Hardware

The README describes an nRF51822 nRF51 ARM Cortex-M0 handling OLED, BLE, battery management, and LEDs, paired with an STM32F072CB ARM Cortex-M0 handling touch buttons and USB. It documents SWD access, STM32 USB DFU flashing, Nordic SDK and SoftDevice dependencies, and available schematic material.

Software & Apps

The firmware path used Nordic SDK 6.1.0, S110 SoftDevice 7.0.0, STM32CUBE, Makefile-based builds, SWD flashing, STM32 USB DFU, and caveats around nonfree SDK and linker-script licensing.

Lore

NorthSec's official past-editions page says 2016 added training sessions and gave a hardware badge to every conference and competition attendee, expanding beyond the per-team hardware-badge distribution used in 2015.

Operational history

Issues & Camp Impact

license dependency caveat note

The README notes nonfree Nordic SDK, SoftDevice, and Atollic linker-script dependencies around the public firmware workflow.

The catalogue treats the hardware and source trail as public but does not imply that every upstream dependency is freely redistributable.

Confidence: primary README
Status: documented
Timeframe: 2016 firmware build
Source note: NorthSec 2016 badge README.

missing rights-cleared image note

No 2016 badge image is published locally because this pass did not verify source URL, license or permission basis, attribution, processing notes, and documentary-photo or official-raster provenance for a specific image.

The record remains text-source complete while avoiding generated, placeholder, or uncleared imagery.

Confidence: policy decision
Status: open
Timeframe: current catalogue build
