Why It Mattered

IoTuz captures the Australasian Open Hardware Miniconf's transition from ESP8266-era workshop badges into early ESP32 badgelife, with public KiCad hardware, firmware, assembly guidance, and a substantial post-event driver ecosystem.

Hardware

The CCHS Melbourne hardware repository describes the board as the linux.conf.au 2017 Open Hardware Project built around the ESP32, with 2.4 GHz WiFi, Bluetooth, dual-core CPUs, custom board files, assembly instructions, KiCad hardware, and repository-documented peripherals including TFT, touchscreen, rotary encoder, buttons, joystick, color LEDs, accelerometer, BME280 sensor, PCF8574 I/O expander, IR receiver, and CP2102 USB serial setup notes.

Software & Apps

The firmware repository provides the Linux Conf 2017 IoTuz firmware with ESP-IDF, WiFi and MQTT configuration, build/flash instructions, and an Apache-2.0 license. The workshop wiki says IoTuz used ESP-IDF at its core, linked the firmware project, documented menuconfig, flashing, serial monitor, MQTT output, and Arduino test-code paths, while Marc Merlin's driver work added Arduino-environment support for many board peripherals.

Lore

The official Tuesday schedule put Open Hardware in Wellington Room 2 with a kit assembly session followed by ESP32, IoTuz hardware, ESP-IDF, MicroPython, and IoTuz demo talks. The repository credits the 2017 linux.conf.au Open Hardware Team and records Tasmanian Devil artwork used for the PCB production run.

Issues & Camp Impact

image provenance upgrade note

The IoTuz visual uses the official `Case/Printable/front-shot.jpg` repository photo under the repository LICENSE statement covering photos and other documentation as Creative Commons Attribution Share-Alike 3.0.

The public badge page, image archive, and API now point at a real upstream IoTuz photo with source URL, license, attribution, and processing notes preserved.

Confidence: official repository license and exact photo source
Status: licensed original photo applied
Timeframe: current catalogue build
Source note: CCHS-Melbourne/iotuz-esp32-hardware repository LICENSE, official `Case/Printable/front-shot.jpg`, and badge.gallery image policy.

revision and source-depth caveat note

The public trail proves the IoTuz project, board files, firmware, assembly guidance, and workshop use, but this pass has not audited exact production-run revision, BOM state, manufacturing quantity, or whether every repository image and file maps to the distributed boards.

The badge dossier cites public hardware and software archives while avoiding unsupported production-run claims.

Confidence: source-backed but historical
Status: needs board-revision audit
Timeframe: 2017 badge archive pass
Source note: CCHS Melbourne hardware/firmware repositories, software wiki, and linux.conf.au 2017 schedule.
