README
README.mdEdge AI Foundation Badge
The Edge AI Badge lets you plug-and-play with the latest vendor hardware at conference workshops and wirelessly connect with other attendees! Use the badge to explore the Edge AI curriculum, plug into sensors, and start building apps.
Hardware
The badge is a modular PCB that allows you to customize your own face & backplates - the hardware platform is consistent at future conferences and makes it easy for attendees to design their own add-ons, or vendors that want to contribute hardware.
It's built around the ESP32-S3, selected for its cryptographic core + secure boot, communication protocols (WiFi, BLE, ESP-NOW), infrared hardware, native USB, and ubiquitous support.

Questions
How big is the Edge AI Badge Main PCB?
It measures 76.5 × 76.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Edge AI Badge Main use?
136 parts, built around the ESP32-S3-WROOM-1-N8, SY8089A, BQ24079RGT and TSOP75338TT. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Edge AI Badge Main KiCad files?
From the LyndLabs/Edge-AI-Badge repository on GitHub, at the commit this page was made from: the board is pcb/badge-main/Edge-AI-Badge_Main.kicad_pcb and its schematic pcb/badge-back/Edge-AI-Badge_Back.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Edge AI Badge Main design in my own project?
Its repository states no licence, so its author keeps all rights: ask LyndLabs before reusing the design.
