Product Description
SIM7070G GSM Module NB-IoT eMTC LTE-CAT-M1 Quad-Band 4G Network for Arduino
Description:
Power supply: 5-12V
Power pins: POWER and GND
Input current: Max is 2A
This shield has a set a TTL UART serial, which is capable with 5v system or 3.3V system. When controller is 3.3v system, you need connect V_MCU pin to 3.3V; when controller is 5v system, you need connect VDD pin to 5V.
TXD is Transmit data pin of UNV-SIM7070X; RXD is Receive data pin of UNV-SIM7070X; DTR is DTE get ready pin, if unused this pin, keep it open.
Then connect USB-TTL module to TTL UART. The hardware connection between USB-TTL and UNV-SIM7O70X module as below:
USB-TTL        SIM7070G
GND               GND
RXD               TXD
TXD                RXD
3.3V                V_MCU
Note: The SIM7070x contains a USB interface compliant with USB2.0 specification as a peripheral, but USB charging function is not supported.
Package Includes:
1 x SIM7070G NB IOT Module Breakout
1  x USB to 2pin dunpont wire (Only power function,
not data
cable)
1 x CP2102 USB to TTL
