BTTM - codename: Flavona

BTTM: Brake & Tire Temperature Monitor A motorsport telemetry system for real-time thermal monitoring of racing vehicle performance. BTTM integrates distributed infrared and RTD temperature sensors across tire and brake systems, reporting via CAN bus to a central ESP32-S3 hub with WiFi telemetry, local web interface, and on-board data logging. Features

Multi-node CAN architecture with dedicated brake and tire sensor nodes Infrared temperature detection Central monitoring unit with ESP32-S3 microcontroller Real-time web telemetry dashboard over WiFi Local TFT display for trackside feedback High-frequency data logging and cloud backup integration Mesh networking support for extended track coverage

Hardware

• ESP32-S3 main hub (ver 1.2)
• ESP32-C3 CAN node IR Sensors (ver 1.1)

All PCB designs are custom.

Applications

Designed for circuit racing, track days, and motorsport testing to provide real-time thermal diagnostics for race strategy, vehicle setup optimization and R&D.
