ESP32 CAN Bus Vehicle Data Reader Kit: Build Your Own Wireless Dashboard

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Imagine pulling real-time RPM and vehicle speed straight from your car's OBD-II port and streaming it wirelessly to an OLED screen you built yourself. This kit puts automotive CAN bus technology directly into your hands, turning raw vehicle data into a sleek digital dashboard using the ESP32 and MCP2515 CAN controller. No more guessing what's happening under the bonnet — now you can code, read, and display it.

What You'll Build

You'll assemble a working OBD-II data reader that captures live RPM and speed PIDs from any OBD-II compliant vehicle, processes the CAN frames with the MCP2515, and pushes the values to a crisp 0.96-inch OLED display over the ESP32’s WiFi. The final build sits neatly on a breadboard, ready to plug into your car’s diagnostic port and start logging — a real IoT dashboard that moves with you.

What You'll Learn

• Decode standard OBD-II PIDs for RPM and vehicle speed using the MCP2515 CAN controller
• Interface the MCP2515 with an ESP32 over SPI and handle CAN bus interrupts
• Transmit live sensor data via WiFi to a local web dashboard or a 0.96-inch OLED display
• Interpret CAN frame structure and apply filter/mask settings for specific vehicle messages
