The Pi2 or Pi3 is normally used with the SHARI Pi3(U) ,while the Pi4 is normally used with the SHARI Pi4(U) 3.A case for the Raspberry Pi. A metal case is preferred but if you want to use a WiFi connection instead of a wired network connection then a plastic case may be required to obtain adequate range. 4.A micro SD card 16GB or larger, Class 10 or better is recommended. 5.A power supply for the Pi-This should be a power supply intended for the version of the Raspberry Pi. These supplies typically provide 5.1 to 5.2 VDC to the Pi. Current requirements vary with version. Numerous problems with Allstar Nodes have been traced to inadequate power supplies.
