Product Description

Mini Size,  Saves Space

The TB601 is a high-performance, low-power, single-mode NB-IoT module with a built-in carrier chip SIM card (eSIM). The LGA package is small and lightweight, The module has low power consumption, wide operating temperature range, and excellent RF performance. It is the best choice for energy metering, intelligent door lock, safety, environmental monitoring and other scenarios.


Strong link: In the case of the same base station, the NB-IoT module is 50 to 100 times more than the existing wireless technology access;
High coverage: NB-IoT has strong indoor coverage and 20dB gain over LTE technology, which is equivalent to an increase of 100 times coverage area;
Low power consumption: sleep current <0.5uA, ER26500 or ER34615 battery power supply, half a month communication, theoretically power supply can reach more than 10 years;
Low cost: Compared with the LoRa module, the NB-IoT does not need to be rebuilt, and the radio and antenna are basically multiplexed;
