This module is powered by 5V, and the computer can debug USB to TTL serial port. The power supply
can output a current of 800MA, and the TTL serial port is compatible with 3.3V and 5V microcontrollers.
After purchase, it can be directly connected to the microcontroller. The IPX antenna interface allows for
arbitrary switching of PCB antennas, stick antennas, and suction cup antennas. SIM800L data 4-band
communication, available globally.
Main Features:
1: The ultra small size is suitable for various cuff and embedded designs. 2: Self elastic card slot for easy replacement of mobile phone cards. It can be placed on one side of the box to reserve a replacement phone slot.
3: Adopting IPX interface, the antenna can be replaced at will. Default PCB antenna greatly reduces usage space. 4: The board is made of gold-plated board, which is more stable in terms of performance. 5: Regular wiring ensures more stable operation of the board. 6: Adding a protective device to this module can achieve anti reverse connection, anti high voltage, and reduce board loss, making it suitable for project and learning.
