โมดูล SIM800L พร้อมเสาสัญญาณ SIM800L module replaces SIM900A, SMS data GSM GPRS 4-band available 5V serial port

โมดูลนี้รองรับแรงดันไฟ 5V ดังนั้นสามารถใช้คู่กับ TTL to USB เพื่อ debug จาก terminal ในคอมได้ทันที แต่ต้องใช้ไฟเลี้ยงที่จ่ายกระแสได้มากกว่า 800mA (ใช้ไฟ USB จากคอมไม่ได้) 

The power supply of this module is 5 V , and the computer can debug the USB to TTL serial port. The power supply can output a current of 800MA. The TTL serial port is compatible with 3.3V and 5V microcontrollers, and can be directly connected to the microcontroller after purchase.

Product Description

This module power supply of 5V, computer debugging USB to TTL serial port. 800MA power supply output current , TTL serial port compatible with 3.3V and 5V MCU, the MCU can be connected directly.

IPX antenna interface can switch PCB antenna, glue stick antenna and sucker antenna.

SIM800L 4 frequency data communications, globally available.

Feature:

• The ultra-small size for a variety of cuff and embedded.
• Using side slot design, easy to switch phone card when you design it within a case
• IPX interface may optionally replace the antenna. Default PCB antenna, greatly reducing: the use of space.
• board with gold board, in terms of performance more stable.
• More stable because of the golden plated PCB
• This module add protection devices that can be anti-reverse, anti-hypertension, reducing the board’s loss, suitable programs and learning.

Package includes SMA-IPX cable and Rod antenna, as shown in the pictures.
