60K-GL-TE-B-KIT is the new development kit for BC660K-GL module

BC660K-GL is a high-performance LTE Cat NB2 module which supports multiple frequency bands of B1/ 2/ 3/ 4/ 5/ 8/ 12/ 13/ 17/ 18/ 19/ 20/ 25/ 28/ 66/ 70/ 85 with extremely low power consumption. The module’s ultra-compact profile (17.7 mm × 15.8 mm × 2.0 mm) makes it a perfect choice for size-sensitive applications. Designed to be compatible with Quectel GSM/GPRS M66 module and NB-IoT BC66/BC66-NA, BC65 and BC68-GV modules, it provides a flexible and scalable platform for the migration from GSM/GPRS to NB-IoT networks.

BC660K-GL adopts the surface-mount technology, which makes it an ideal solution for durable and rugged designs. The module’s small LCC package allows it to be easily embedded into space-constrained applications and to enjoy reliable connection with the applications. This kind of package suits well large-scale manufacturing which has strict requirements on cost and efficiency.

Due to the ultra-compact profile, super-low power consumption and extended temperature range, BC660K-GL is one of the best choices for a wide range of IoT applications, such as smart metering, bike sharing, smart parking, smart city, smart safety, asset tracking, home appliances, agricultural and environmental monitoring. It is able to provide a complete range of SMS and data transmission services to meet various user demands.
