PuckIt V2 — DIY Driver Alert Button Case

PuckIt V2 is a compact 3D-printable enclosure for a DIY driver-to-driver alert button.

It holds a Seeed XIAO ESP32S3 with Wio-SX1262 LoRa radio, a 30 mm hazard button, a 16 mm Puck Yeah button, and an 8 LED WS2812B light bar.

Designed for grassroots motorsport, drift, track days, private roads, and community builds.

No phone app. No mobile coverage. No subscription.
Press the button. Nearby units can receive the alert and show the LED warning.

This is a prototype/community hardware case. It is a supplemental awareness aid only and is not a safety device.
