Product Concept
BC65-TE-B is a NB-IoT development board which supports Arduino interfaces. Designed in 70.0 mm ×
74.0 mm × 1.6 mm form factor, BC65-TE-B can be used to develop and debug applications which
communicate with mobile network operator
s’ infrastructure equipment through NB-IoT radio protocols
(3GPP Rel-13 and Rel-14).
