NBSFF device was developed for quick start development in the area of NBIoT which is rather complex for first steps in comparison with other LPWAN technologies such as Sigfox or LoRaWAN. The NBSFF contains the following parts:
• NBIoT certified transceiver Quectel BC66
• eSIM (Vodafone or T-Mobile)
• xmega32e5 MCU for interfacing over UART and NBIoT stack
