Compact NB-IoT Module

BC66 is a high-performance NB-IoT module with extremely low power consumption. The ultra-compact 17.7mm × 15.8mm × 2.3mm profile 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. BC66 provides abundant external interfaces and protocol stacks and also supports OneNet Cloud platform, providing great convenience for customers' applications.

BC66 adopts surface mounted technology, making it an ideal solution for durable and rugged designs. The low profile and small size of LCC package allow BC66 to be easily embedded into space-constrained applications and provide reliable connectivity with the applications.

Due to compact form factor, ultra-low power consumption and extended temperature range, BC66 is a best choice for a wide range of IoT applications, such as smart metering, bike sharing, smart wearable, 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.
