Beebird Labs builds open tooling for Toyota BEAN/IoT systems — from Python bus decoders to ESP MCU-based readers. Mostly JDM, with occasional distractions.
// public_now
Tools, readers, and simulators for Toyota BEAN bus systems and IoT tinkering. All GPL-3.0 licensed and available on GitHub.
Python tools and reference notes for working with Toyota BEAN bus messages. The foundation of the whole ecosystem.
An ESP8266-based BEAN bus reader that captures specific messages and re-broadcasts them wirelessly via ESPNow.
Reads speedometer data from Toyota vehicles and transmits speed readings out over ESPNow for downstream processing.
A vehicle speed signal simulator built on the Arduino UNO R4. Designed for bench-testing speedometer readers without a real car.
// about
Beebird Labs is an independent electronics lab focused on JDM vehicle systems and IoT tooling. We reverse-engineer, document, and build open-source tools for Toyota platforms — starting with the BEAN bus.
