Description:
The sim900a is a dual band module gsm 900 / 1800 mhz that supports voice call, sms and gprs. But it doesn 't have jack audio on board, which means you can' t hear or talk over the call.
Feature:
- power supply by 5v, powered by usb, for longer-term use better using its own 1a power supply with xh2.54-2p connector.
- ttl 5v and 3v3 (yellow pin marked on board), compatible with arduino, stm32, raspberry pi, etc.
- onboard rs232 is easy to debugging. On the left, white pin.
- on the board there 's a led signal on the left. - top of the sim900a ic angle.
On board reboot and restart pin, at the bottom of sim900a ic.
- it has a mini ipx connector, but it hasn 't been held.
- standard sma antenna connector.
- serial port protected by tvs to prevent a surge in current or hv.
- sim circuits have smf05c electrostatics releasing ic.
- packages include antennas and dc jacks.

[Kamemb] SIM900A Kit Wireless Extension Module GSM GPRS Board Antenna for arduino******************Welcome to our Kamemb***********************Features:
The onboard two set power supply interface VCC5 5V power supply, VCC4 interface, 3.5--4.5V power supply, optional power on self starting (default) and control start.
The onboard SMA (default) and IPXmini antenna interface, SIM900A interface reserved reset.
The size of the module is 49*50, all the new and original device.
The computer can give early computer debugging USB module power supply, a very large amount of data under the condition of the recommended current more than 1A. Standby dozens of MA data can be set to provide dormancy, dormancy of 10MA low power. Support 2, mobile phone 3,4G card.
The serial port circuit: support for 3.3V single chip microcomputer. TTL serial port support
3.3 and 5V single chip microcomputer.
The SIM card circuit to increase the SMF05C ESD chip.
Antenna circuit: guarantee short and straight, so as to ensure the signal strength.
PCB display screen printing mark: each interface, convenient development two times, the SIM900/A hardware is completely follow the design when the design manual.
Two power supply interface: VCC5, 5V DC above 1A. Computer 5V power supply can be early computer USB. DC long data circuit over larger recommended 5V1A. VCC4, 3.5--4.5V power supply, ibid., suitable for lithium battery.
Control pin all leads.
A TTL level, compatible with 3.3V and 5V.
The two antenna interface, the default SMA straight head, connector for IPXmini antenna.
One way of speech interface, the way Mike interface.

This module advantages:
Circuit: The tvs and bead protection devices to protect the board so that
The board will not be a surge, high voltage damage.
Sim card circuit: Increase smf05c electrostatic chip rechargeable.
The antenna circuit: To ensure short and straight, so as to ensure that the
Signal strength.
Silk mark each interface, convenient secondary development full pcb show
Compliance with sim900a hardware design manual design.
A 5v power supply interface: We do protection, even reversed, it will not burn
The board. Early computer debugging usb-powered computer can; for a long time
To transfer data assumption greater than 1a dc we recommend.
All the way ttl interface: Supports 3.3v and 5v mcu mcu. That kind of support 5v
Microcontroller 51 and stm32 microcontroller.
Two antenna interface: Sma antenna interface, ipx mini antenna interface (the
Default is not welding).
All the way to 232-level interface: That you can directly connect the module to
The computer via a rs 232 - - usb serial cable. You can also usb - ttl connected
To the computer, based on individual parts circumsta
