Product Concept
BC66-TE-B is a NB-IoT development board which supports Arduino interface. Designed in 70.0mm ×
74.0mm × 1.6mm form factor, BC66-TE-B can be used either alone or in conjunction with STM32
Nucleo-64 development board, so as to develop and debug applications which communicate with
infrastructures of mobile network operators through NB-IoT radio protocols in 3GPP Rel. 13.

UART Switch
Used to switch the communication object of BC66 main UART port
USB Interface
Support three UART ports
Main UART (Interface0):
Used for AT command communication and data transmission.
By default, the module is in auto-baud mode, and it supports
automatic baud rates not exceeding 115200bps. When powering on
the module, the MCU has to send
AT
command consecutively to
synchronize baud rate with the module. When
OK
is returned, it
