1pc/2pcs/5pcs SIM7070G NB-IoT Breakout Module Multi-Band UART GPIO SPI I2C GPRS GNSS Expansion Board FZ5144
Power supply: 5-12V
Power pins: POWER and GND
Input current: Max is 2A
The SIM7070G is Multi-Band CAT-M, NB-IoT and GPRS 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, this module is ideally suited for M2M applications, such as metering, asset tracking, remote monitoring , E-health etc..
This 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-SIM7070X; RXD is the Receive data pin of UNV-SIM7070X; 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:
Note: The SIM7070x contains a USB interface compliant with the USB2.0 specification as a peripheral, but the USB charging function is not supported.
