Customer Reviews

The controller is essentially a shield for any Raspberry Pi with a 40 pin I/O header. If you use a Pi 3 or 4 two of the edges line up with the controller board so you have access to the USB ports, Ethernet, HDMI and audio ports externally when the board is put in a case. You can use a Pi Zero W or Pi Zero 2 W but won't have external access to its ports.
