  • GND – ground

SIM800L GPRS GSM Module Micro SIM Card Core Board Quad-band TTL Serial Port

SIM800L GPRS GSM Module Micro SIM Card Core Board Quad-band TTL Serial Port breakout board is based on available for GPRS and SMS message data remote transmission. The board features compact size and low current consumption. With the power-saving technique, the current consumption is as low as 1mA in sleep mode. It communicates with the microcontroller via UART port, supports command including 3GPP TS 27.007, 27.005 and SIMCOM enhanced AT Commands. The serial port is a TTL serial port, which can be directly linked with the MCU. Module power-on automatically starts, automatically finds the network On-board signal indicator (slow signal flashing, no signal flashing)
