ITEM NAME:SIM800L GPRS GSM Module PCB Antenna SIM Board Quad band for MCU Arduino UCQ CFO Descriptio n Features: Network support: Quad-Band 850/900/1800/1900 MHz – works on GSM networks in all countries across the world. TTL serial interface compatible with 3.3V and 5V MCU The small size is suitable for all kinds of sleeve belt type and embedded. playing card slot, convenient change mobile phone card.Can side reserve replacement cell phone bayonet into the box. using the IPX interface can arbitrarily change the antenna. The default PCB antenna greatly reduces: use the space. the board with gold plated board, more stable performance. when wiring neat guarantee board running more stable. this module adds a protection device, which can realize the prevention, high pressure, reduce the loss of the board, suitable for the project and learn. Pin Description: 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.
