Apart from the controller HAT project, several other Pi projects have been undertaken. These include an SDR based weather receiver and NOAA message decoder, linking software for the repeaters, remote access to the AREDN network using packet radio.

Other HATS in development include an AZ/EL rotator control, an MMDVM hotspot, and a Power HAT for 12v/POE applications.

A shelf of Pis was also built to accommodate the AREDN applications, complete with a node for Wifi access.
