EC-01 is a NB module developed by Ai-Thinker. The main chip scheme adopted by the NB part is EC616S. The chip has an ultra-highly integrated NB-IoT SoC, supports ultra-low power consumption, and fully supports the 3GPP Rel14 NB-IoT standard. It is an ultra-high cost-effective NB-IoT chip. It has the following characteristics：

1. Integrated RF transceiver, PA, RF filter, antenna switch and power management. 

2. Excellent communication performance and stability in various wireless environments.

3. Excellent power consumption performance in various modes (PSM, DRX, eDRX, connected state). 

4. Unique MCU mode, providing lower working current and shorter wake-up time.
