The BC20 is a high performance, low power, multi-band, NB-IoT wireless communication module that supports GNSS positioning. Its size is only 18.7mm × 16.0mm × 2.1mm, which can meet the needs of terminal equipment for small-sized module products, and help customers reduce product size and optimize product cost.
The BC20 is designed to be compatible with the MC20 module of the GSM/GPRS/GNSS series of mobile communication, allowing customers to quickly and flexibly design and upgrade their products. The BC20 provides a rich set of external interfaces and protocol stacks, and supports China Mobile's OneNET IoT cloud platform, providing great convenience for customers' applications.
The BC20 supports demodulation algorithms for multi-constellation satellite systems such as Beidou, GPS, and QZSS. Its positioning is more accurate, and it is more resistant to multipath interference. It has more advantages than traditional single GPS modules. In addition, the BC20 module has built-in LNA and low-power algorithms: the former guarantees higher sensitivity and the latter guarantees lower current consumption in low-power mode.
The BC20 module is 40% smaller than the traditional NB-IoT+GNSS solution. With its compact size, ultra-low power consumption and wide operating temperature range, the BC20 has a greater advantage in a variety of applications; its main application areas are: bicycle and motorcycle theft, pet tracking, financial property tracking and driving recorders. and many more.

Q1: Are your products original?
Yes, our products are 100% original.
Q.2:How does your factory to control the quality?
We are always adhering to the principle that quality is the core from the production to shipping.
Q.3:What are the main export countries?
Our products are sold worldwide. The main market is in Europe.
Q.4.What could be the reason why the call somehow hangs off when you use ATD to make a call?
1. Check if MCU sends ATH command to close the call.
2. Check whether there are capacitors with high capacitance like more than 1uF in the audio interface. In general，only 10pf and 33pf capacitor can be connected to the audio interface to eliminate the RF interference. Capacitor with high capacitance will cause the instability of audio PA, which may lead to the call hanged off.
