2.1. General Description
BC660K-GL is a high-performance NB-IoT module with extremely low power consumption. It is designed
to communicate with infrastructures of mobile network operators through NB-IoT radio protocols 3GPP
Rel-13 and Rel-14. BC660K-GL supports a broad range of frequency bands as listed below.
Table 1: Frequency Bands of BC660K-GL
BC660K-GL is an SMD type module with LCC and LGA package, and has an ultra-compact profile of
17.7 mm × 15.8 mm × 2.0 mm, which makes it easily embedded into size-constrained applications and
provide reliable connectivity with the applications.
BC660K-GL provides abundant external interfaces (UART, ADC, USIM, etc.) and protocol stacks
(UDP/TCP/LwM2M*/MQTT*, etc.), which facilitates the module’s application.
The module’s compact form factor, ultra-low power consumption and extended temperature range makes
it one of the best choices for a wide range of IoT application, such as smart metering, bike sharing, smart
wearables, smart parking, smart city, home appliances, security and asset tracking, agricultural and
environmental monitoring, etc. It also provides a complete range of SMS* and data transmission services
to meet various user demands.
The module fully complies with the RoHS directive of the European Union.
