EC-01F module introduction:

EC-01F is an NB module developed by Essence. The main chip solution used in the NB part is EC616S. This
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 extremely cost-effective NB-IoT chip.

EC-01F module features:

Integrated RF transceiver, PA, RF filter, antenna switch and power management.
Excellent communication performance and stability in various wireless environments.
Excellent power consumption performance in various modes (PSM, DRX, eDRX, connected state).
Unique MCU mode provides lower operating current and shorter wake-up time

Basic parameters of the adapter board:

1. Uses Type-C interface for power supply and 5p external serial port communication. Can be used for secondary development

2. The serial port chip uses CH340K, which has a smaller package size.

3. Onboard power indicator light, NB status indicator light, and networking indicator light.

4. The current version supports SIM cards. If an ESIM card is needed, it can be modified twice according to the schematic diagram.
