Description
Commonly used with arduino, esp8266, esp32, rpi, opi to add GSM/SMS/DIAL/GPRS (mobile data) capability to your projects.
SIM800L V2.0 5V Wireless GSM GPRS MODULE power supply for 5 v, computer debug USB to TTL serial port. Power to the output current of 800 ma, TTL serial interface is compatible with 3.3 V and 5 V micro-controller, can be directly after purchase and single-chip computer connection.
SIM800L V2.0 GSM/GPRS Module is a QUAD-BAND GSM/GPRS module which compatible with Arduino. The module works both of GSM features (voice call or SMS) and GPRS features. The advantages of these modules are the VCC and TTL serial levels that have 5V voltage, so you can directly connect it to Arduino or another minimum system with 5V of the voltage level.
Wiring
5v: Power interface Power the module CONNECT TO DC 5v
GND: Connect to GND.
VDD: TTL UART interface The TTL UART serial interface, you can connect the MCU like 51MCU or ARM or MSP430 directly. The pin of VDD is used to match the voltage of the TTL.
SIM_TXD: SIM module Transmitter.
SIM_RXD: SIM module Receiver.
GND: If this pin is unused, keep open.
RST: RST the module, if this pin is unused, keep open.
Network support: Quad-Band 850/900/1800/1900 MHz – works on GSM networks in all countries across the world.
Serial: TTL serial interface compatible with 3.3V and 5V MCU
Work voltage: 3.7~5V
Operation temperature : -40°C to +85 °C
Dimensions: 15.8*17.8*2.4mm
