Product Concept
BC95-GR-TE-B is an NB-IoT development board which supports Arduino interfaces. Designed in
70.0 mm × 74.0 mm × 1.6 mm form factor, BC95-GR-TE-B can be used to develop and debug
applications
which communicate with mobile network operators’ infrastructure equipment through NB-IoT
radio protocols (3GPP Rel-13 and Rel-14).
