GSM GPRS Module SIM800L V2 - Updated 2G Module proximity sensor Product Sensor style Standout IRCompact quad band GSM GPRS module for adding 2G cellular to a project. Send SMS, make calls, or push data over GPRS. Talks to your microcontroller over a plain TTL serial link with AT commands, so it pairs easily with Arduino, ESP, or a Pi. Note the power draw: it needs 3. 4 4. 4V and can pull 1A+ in bursts during transmit. A weak 3. 3V pin off a dev board won't cut it, use a dedicated supply. Specs Bands Quad band 850 900 1800 1900MHz Supply 3. 4 4.
