Ultra-compact Multi-band NB-IoT Module

BC68 is a high-performance NB-IoT module which supports multiple frequency bands of B1/B3/B5/B8/B20/B28 with extremely low power consumption. The ultra-compact 17.7mm × 15.8mm × 2.0mm form factor makes it a perfect choice for size sensitive applications. Designed to be compatible with Quectel GSM/GPRS M66 module in the compact and unified form factor, it provides a flexible and scalable platform for migrating from GSM/GPRS to NB-IoT networks.

BC68 adopts surface mounted technology, making it an ideal solution for durable and rugged designs. The low profile and small size of LCC package allow BC68 to be easily embedded into space-constrained applications and provide reliable connectivity with the applications. This kind of package is ideally suited for large-scale manufacturing which has strict requirements for cost and efficency.

Due to compact form factor, ultra-low power consumption and extended temperature range, BC68 is the best choice for a wide range of IoT applications, such as smart metering, bike sharing, smart parking, smart city, security and asset tracking, home appliances, agricultural and environmental monitoring, etc. It is able to provide a complete range of SMS* and data transmission services to meet client-side demands.
