HiP Berlin 2022 Badge
source-backed
NFC and SAO expansion surface
The documented board exposes I2C through SAO headers and includes an ST25DV04K NFC/I2C EEPROM for badge experiments.

USB-C Serial/JTAG badge-hacking path
The badge could be connected to a laptop by USB-C for development, with RIOT OS documenting Serial/JTAG flashing and manual bootloader recovery steps.

37C3 take-home reuse workshop
At 37C3, Hardware Hacking Area mentors provided HiP badges to teams for embedded-programming practice and allowed the devices to be taken home after the showcase.

Sixteen WS2812B LEDs
RIOT OS board documentation lists 16 WS2812B LEDs, while the 37C3 workshop source describes the badge as having many RGB LED lights.
Operational history
Issues & Camp Impact
No HiP badge image is published because the recovered photo metadata identifies a real photo and copyright holder but does not provide an explicit reusable license, attribution string, and processing record for badge.gallery.
The record remains source-backed and image-free rather than copying a wiki, event, or documentation image without complete rights provenance.
The 37C3 workshop used remaining HiP badges as free team hardware for learning, not as 37C3 official attendee badges.
The record treats 37C3 as lifecycle and reuse evidence while keeping the badge assigned to Hacking in Parallel Berlin 2022.
The 37C3 workshop advertised a TVOC air-quality sensor, but RIOT OS notes that the SGP30 sensor was only populated on some boards.
The hardware description keeps the TVOC claim tied to source context and records that not every physical badge necessarily carried the same populated sensor set.
RIOT OS documentation says the event and badge were organized in about six weeks and records hardware issues around the missing WiFi/BLE antenna connection, broken IR transceiver, partially populated SGP30 sensor, and missing MAX17048 fuel gauge.
The catalogue records the shipped board as a real attendee badge while preserving the known build limitations.
