Product Name
STM32 4G Networking MOSFET Switch Development Board Air780e Module
Regarding LC-IOT-1023
Air780E is an LTE Cat.1 bis communication module launched by Luat Communication. It is a 4G full network and can adapt to different operators and products.
By default, it uses AT firmware to communicate with STM32 through serial port and uses AT commands for networking data transmission and reception

Instructions for use
MOS transistor output wiring method:
VCC: Connect to load for power supply
MOT+: Connected to the positive pole of the load, MOT+is connected to VCC
MOT -: Connect the negative pole of the load
GND: The power supply GND of the load needs to be connected to the GND of the control terminal and connected to the board
+5V: The control terminal is powered by+5V and is responsible for supplying power to microcontrollers and other devices. Overvoltage should not be exceeded
The default program is STM32 to send AT commands requesting Air780e to connect to the network. If the connection is successful, the MOS transistor will be turned on
Prepare a USB to serial port connection to the board, connect PA9 to RX, PA10 to TX, and GND to GND
The SIM card must be connected before powering on, and the board will automatically connect to the internet and turn on the MOS transistor
