+OpenDIAG is an open source OBD2 diagnostic interface for reading and clearing
+vehicle diagnostic trouble codes, streaming live sensor data, and accessing
+manufacturer-specific ECU functions. The device presents itself as a USB CDC
+serial port to the host.
+
+The hardware is an ESP32-S3 based board using the chip's native USB and TWAI
+(CAN) peripherals, with a CAN transceiver, K-line, and J1850 PWM/VPW
+interfaces published under CERN-OHL-S-2.0 at
+[opendiag-hardware](https://github.com/maximus64/opendiag-hardware). The
+firmware is licensed GPLv3 at
+[opendiag-firmware](https://github.com/maximus64/opendiag-firmware), and a
+companion host-side tool is available at
+[opendiag-cli](https://github.com/maximus64/opendiag-cli).
