Description: The SIM7000A is Multi-Band LTE FDD module solution in a SMT 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 etc. The module provides much flexibility and ease of integration for customer's application.
The package of SIM7000A is compatible with SIM900 and SIM800F. AT commands of SIM7000A 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.

You can't connect the micro USB interface to power the board directly, you need to power it via the USB to 2Pin cable, or 5V VCC Pin on MCU, but the latter not recommended.
You need use Arduino Uno or Serial module to connect with SIM7000A board.
To send AT command via serial interface, please ensure Power pin and V_MCU pin on sim7000a board are connected with 5V.
Connection for SIM7000A and Uno: Power -- 5V GND -- GND TXD -- RXD RXD -- TXD V_MCU -- 5V
Connection for SIM7000A and Serial module:
Note: you need install driver for the serial module and switch it to 3.3V
GND -- GND TXD -- RXD RXD -- TXD V_MCU -- 5V
SIM7000A with USB cable
Power -- Red Wire
GND -- Black Wire
Software: You can use SSCOM or other Serial port software.
