The controller shield is a GPIO breakout to screw terminal board for the raspberry pi that allows for easy end unit development. There are IDC headers to connect supported expansion modules and get rid of those jumper wires. On board DHT temperature sensor support as well as other various pull down resistors and status LEDs.
This board was designed to connect using a 40 pin IDC ribbon cable to the pi to allow stacking for both on top or below a raspberry pi using the provided mounting holes. (Typically mounting the pi on top is preferred to allow more airflow)
MudPi is still being developed and updated with new features. Want to know when we launch? Drop your email and I will contact you once or twice a month with the latest updates.
