Arduino UNO R3 Official Genuine Version + USB Cable so you can directly connect

so you can directly connect it to Arduino or another minimum system with 5V of the voltage level

Accuracy: ~2

Antenna interface circuit(SMA bend female port)

There are so many GPRS/GSM modules on the market which need to add 5V regulator and level converter circuit
