ماژول GSM  بسیار کوچک با قابلیت اتصال GPRS و ارسال و دریافت پیامک Sim900A

Features:
The ultra-small size for a variety of cuff and embedded.
Since the bomb slot, easy to replace the phone card. You can put the box aside reserve replacement phone mount.
IPX interface, which could be the replacement antenna. Default PCB antenna, greatly reducing: the use of space.
board with gold board, in terms of more consistent performance.
structured wiring board to ensure that time is running more stable.
This module plus a protective device, enabling anti-reverse, anti-hypertension, reduce the loss of the board, suitable for the project and learning.

Functionality:
Phone: cell phones and we can make and receive calls, a call instruction "ATD150 **** 5417 ; enter "on the line.
SMS: text messaging, you can send a message to their own devices, motion control him! When equipment fails, it can alert to you!
GPRS: Embedded TCP / IP protocol, direct and fixed public ip of computer communications, extensive data monitoring.
MMS: MMS; can send pictures that are very useful in the field of security and smart home!
DTMF: Dual tone multi-frequency, that is, during a call via the serial port that can be read by other key, and we hit 10086, automated voice so that we select press 1, 2, 3 the same. We can control the device through this action, the remote control alone.

Improvements:
SIM card chip circuitry increases SMF05C electrostatic discharge.
antenna circuit: to ensure short and straight, so as to ensure that the signal strength.
PCB Show: silk mark each interface, convenient secondary development, in full compliance with the design SIM900A hardware design manual design.
antenna interface: IPX interface, comes with built-in PCB antenna GSM dedicated, saving space.
all the way to 5V power supply connector. USB-powered computer can, because we added a super tantalum capacitors.
the way TTL interface: Supports 3.3V and 5V microcontrollers microcontrollers. That kind of support 51 5V microcontroller and STM32 microcontroller
