It connects via the camera's M8 interface and adds 16 GPIOs, four 16A SPDT relays, CAN 2.0 (up to 1 Mbps), RS232, two USB 2.0 ports, an isolated strobe output, onboard audio, and status LEDs. Powered by an RP2040 MCU, it draws power directly from the OAK4 M8 connector with no external supply needed. The module supports DIN rail and VESA mounting, making it suitable for machine vision and factory automation. GPIO and peripheral control are exposed via the u2if protocol, with Python examples available on GitHub covering relay control, CAN communication, GPIO, and barcode detection. The PR1 prototype is available for $249 and is intended for professional and development use only. ## Full article daily.dev links to this article rather than hosting it.
