2 Product Concept
BC660K-GL-TE-B is a NB-IoT development board which supports Arduino interface. Designed in the form
factor of 70.0 mm × 74.0 mm × 1.6 mm, BC660K-GL-TE-B can be used alone or in conjunction with an
STM32 Nucleo-64 development board to develop and debug applications which communicate with the
infrastructure of mobile network operators through NB-IoT radio protocols in 3GPP Rel-13 and Rel-14.
