The Notecard and its companion Notecarrier-Pi HAT support virtually any Raspberry Pi-compatible single-board computer (SBC) with a 40-pin male header connector. An example of a compatible SBCs is the balenaFin.
Note that due to the power requirements of the Notecard, some Raspberry Pi 2 and 3 models include a current-limiting fuse that will power-cycle the device when the Notecard’s modem is on and transmitting. To avoid these issues, we recommend using Raspberry Pi 4 devices with the Notecard and Notecarrier Pi HAT.
