SIM800L Mini GSM Module

This is a Mini GSM / GPRS breakout board is based on SIM800L module, supports quad-band GSM/GPRS network, available for GPRS and SMS message data remote transmission. The board features compact size and low current consumption. With power saving technique, the current consumption is as low as 1m A in sleep mode.

SIM800 is communicates with microcontroller via UART port, supports command including 3GPP TS 27.007, 27.005 and SIM COM enhanced AT Commands.

Features of SIM800 Mini GSM

• Quad-band 850/900/1800/1900MHz - connect onto any global GSM network with any 2G SIM (in the USA, T-Mobile is suggested).

• Make and receive voice calls using a headset or an external 8Ω speaker and electret microphone.

• PWM/Buzzer vibrational motor control

• AT command interface with "auto baud" detection

• Send and receive SMS messages.

• Send and receive GPRS data (TCP/IP, HTTP, etc.).

• Scan and receive FM radio broadcasts.

• Lead out buzzer and vibrational motor control port.

• AT command interface with "auto baud" detection.

• Onboard IPEX socket that can be connected to external antenna.

• Breakouts for external 8W speaker and electret mic if you don't want to use a headphone

• Level shifting circuitry so you can run it with 2.8V to 5V logic.

• Vibrational motor (buzzer) driver so you can have noiseless notifications

• uFL or SMA connections for external antenna

• Indicator LEDs for power and network connectivity

• Standard SIM slides into the back
