LCA2019 E-ALE Floral Bonnet

linux.conf.au 2019 hosted the Apprentice Linux Engineer tutorial track in Christchurch, where lab participation required a purchased Floral Bonnet board for Raspberry Pi Zero hands-on embedded-Linux exercises.

Lifecycle

Add-ons & Upgrades

LCA2019 E-ALE Floral Bonnet source-backed

event hardware distribution

ARM-subsidized on-site kit

E-ALE documented a NZD 20 on-site kit price at LCA after ARM sponsorship reduced the original hardware cost.

Compatibility: LCA2019 E-ALE Floral Bonnet

hardware architecture

Floral Bonnet sensor package

The board exposed CP2102 serial-over-USB, SPI SSD1306 OLED, I2C pressure/temperature and light sensors, a GPIO push button, and a PWM tricolor LED for driver-writing exercises.

Compatibility: Raspberry Pi Zero WH

training hardware platform

Raspberry Pi Zero WH lab stack

The E-ALE LCA2019 pages document Raspberry Pi Zero WH lab use and a Floral Bonnet purchase requirement for hands-on seminar work.

training workflow

E-ALE seminar sequence

The LCA2019 E-ALE schedule used the board across a three-day sequence covering walkthrough, GPIO/libgpiod, SPI/spidev, I2C/i2cdev, IoT/cloud, and security topics.

Operational history

Issues & Camp Impact

LCA2019 E-ALE Floral Bonnet note

hardware archive gap · source-backed but incomplete · needs board repository recovery

The recovered source trail documents the board role, Raspberry Pi Zero WH target, major peripherals, lab use, and kit price, but this pass did not recover schematic, PCB, BOM, firmware, or exact sensor-part correction beyond the page text.

The entry keeps claims to the official component list and training context while avoiding unsupported board-revision, driver-source, or manufacturing-quantity details.

LCA2019 E-ALE Floral Bonnet note

missing rights-cleared image · local project policy · needs licensed original replacement

No Floral Bonnet image is published because the recovered E-ALE page images have not been paired with complete image reuse rights, attribution, source URL, and processing notes for catalogue publication.

The record remains source-backed and image-free rather than copying seminar-page photos or publishing generated imagery.

LCA2019 E-ALE Floral Bonnet note

training-artifact classification · primary source · documented

The source trail proves a Floral Bonnet board used for LCA2019 E-ALE labs, but not a conference-wide attendee badge.

The entry is modeled as a hardware training kit in the linux.conf.au/Oceania lineage rather than an official admission badge.
