Features

SIM7080G
CAT-M&NB-IoT Module
The package of SIM7080G is compatible with SIM868.
The SIM7080G is Multi-Band CAT-M and NB-IoT module solution in a SMT type .
It has strong extension capability with rich interfaces including UART, GPIO, PCM, SPI, I2C etc.
The module provides much flexibility and ease of integration for customer's application.
It is designed for applications that need low latency, Low throughput data communication in a variety of radio propagation
conditions.
Due to the unique combination of performance, security and flexibility.
The SIM7080G module is ideally suited for M2M applications, such as metering, asset tracking, remote monitoring , E-health etc..

VCC 2.7V-4.8V
PWRKEY Active low.Power on/Power off/ResetFunction. After the PWRKEY continues topull down more than 12S,the system willautomatically
reset. Therefore, long-termgrounding is not recommended for PWRKEY pin.
TXD 3.3V TTL Series data Output
RXD 3.3V TTL Series data Input

3.2 How to use TXD and RXD

How to use TXD and RXD (Defaultbaud rate is 115200bps)

4.How to test the BK-SIM7080 by AT command via UART

4.1 Installing LTE antenna, GPS antenna and SlM card for BK-SlM7080 Board.(Note: Please use loT card, not normal Mobile phone card.)
4.2 Feed power supply to VCC pin, and pull low PWRKEY pin for 1-2Second andrelease, The Green LED begin to blink.
4.3 GREEN LED indicator, Blink quickly shows un-registration network, Blinkslowly shows registration successful. (Note: Should confirm whether correct SlMcard is inserted)
4.4 Open serial software and choose right serial number, Baud rate as below, please keep“SendNew" selected:

NETLIGHT Pin Status Module Status
64ms ON. 800ms OFF No registered network
64ms ON, 3000ms OFF Registered network (PS domain registration success)
64ms ON. 300ms OFF Data transmit (PPP dial-up state and use of data services such asinternal TCP/FTP/HTTP)
OFF Power off or PSM mode

5. How to test the BK-SlM7080 by AT command via USB

5.1 Remove all connection on CN101 7pin connector, Power up the SlM7080Breakout board only via USB, and pull PWRKEY pin low for 1-2Seconds topower on sim7080 module, Install SIM7070 SIM7080 WIN7 WIN10 US-B Driver V1.00.rardriver following the computer indication. The computer willshow as belows, it means that the driver is installed correctly.
5.2 Select AT Port 9001,115200bps and SendNew, you can repeat all com-mand in ltem4.4.
