GSM 2G Modem with TTL UART
& RS232 UART Port , Operating Voltage 12 VDC, Current Rating (1-2 )Amps
Current, SIMCOM Module SIM800L
Description:
The SIM800L
GSM/GPRS module is a compact and low-power quad-band GSM modem
designed for wireless communication. It enables mobile communication
via voice calls, SMS, and GPRS data transfer using 2G networks.
This module is widely used in IoT applications due to its small size and low
power consumption. It communicates with microcontrollers using AT
commands via a UART (serial) interface.
