SIM800L GSM / GRPS MODULE

SIM800L Quad-band GPRS GSM Module with Micro SIM Card

SIM800L is a miniature cellular module which allows for GPRS transmission, sending and receiving SMS and making and receiving voice calls. Low cost and small footprint and quad band frequency support make this module perfect solution for any project that require long range connectivity. After connecting power module boots up, searches for cellular network and login automatically. On board LED displays connection state (no network coverage – fast blinking, logged in – slow blinking).

NOTICE: Be prepared to handle huge power consumption with peek up to 2A. Maximum voltage on UART in this module is 2.8V. Higher voltage will kill the module.

Two antennas!

This module have two antennas included. First is made of wire (which solders directly to NET pin on PCB) – very useful in narrow places. Second – PCB antenna – with double sided tape and attached pigtail cable with IPX connector. This one have better performance and allows to put your module inside a metal case – as long the antenna is outside.

Module pinout

Pinout (bottom side – left):

• RING (not marked on PBC, first from top, square) – LOW state while receiving call
• DTR – sleep mode. Default in HIGH state (module in sleep mode, serial communication disabled). After setting it in LOW the module will wake up.
• MICP, MICN – microphone (P + / N -)
• SPKP, SPKN – speaker (P + / N -)

Pinout (bottom side – right):

• NET – antenna
• VCC – supply voltage
• RESET – reset
• RXD – serial communication
• TXD – serial communication
• GND – ground
