SIM7000G is Global-Band LTE-FDD, TDD-LTE and Quad-Band GPRS/EDGE module solution in a LCC type which supports LTE CAT-M1(eMTC) and NB-IoT up to 375kbps data transfer. It has strong extension capability with rich interfaces including UART, USB2.0, GPIO. The module provides much flexibility and ease of integration for customer’s application. The package of SIM7000G is compatible with SIM900 and SIM800F. AT commands of SIM7000G are mostly compatible with SIM800F. This also maximizes the investments of customers, and enables a short time-to-market.
It is designed for applications that need low latency, medium throughput data communication in a variety of radio propagation conditions. Due to the unique combination of performance, security and flexibility, this module is ideally suited for M2M applications, such as metering, telematics, asset tracking, remote monitoring, E-health, mobile pos terminals and sharing bike.
Description: Power supply: 5-12V Power pins: POWER and GND Input current: Max is 2A
shield has a set a TTL UART serial, which is capable with 5v system or
3.3V system. When the controller is 3.3v system, you need connect the
V_MCU pin to 3.3V; when the controller is 5V system, you need connect
the VDD pin to 5V.
TXD is the Transmit data pin of UNV-SIM7000G; RXD is the Receive data
pin of UNV-SIM7000G; DTR is the DTE get ready pin, if unused this pin,
keep it open.
Then connect the USB-TTL module to the TTL UART. The hardware connection between the USB-TTL and UNV-SIM7O70X module as below:
