The hardware visible here is an STM32 Nucleo expansion board coupled to a Quectel BG96 LTE Cat M1/Cat NB1/EGPRS module.

And that’s the message that wireless provider Verizon brought to the Tech Tour. It is providing budget-priced communication services aimed at the low-data-rate stuff characterizing IoT applications.
