These are the essentially the OBD item without the OBD shell/connector.

They will expect 12v power input on the through-hole pins, otherwise you could use a USB-C cable for power straight into the ESP32, or solder wire to the 5v pin of the ESP32.

All options with ESP32-S3 processor, WiFi, Bluetooth

Various combinations of additional components available:

• CAN bus + K-line
• CAN bus + Micro-SD card
