GSM GPRS SIM900 Module for Arduino
Non-returnable
BD 18.500
This SIM900 GSM / GPRS Module is useful for using a cell phone network to talk to your microcontrollers wirelessly. Just wire it up to your microcontroller and you’ll have quad-band GSM network access anywhere in the world! Pop in a GSM simcard to send/receive calls and messages from your projects like you would with a cell phone. There are three protocols you can use to send messages: Short Message Service, Audio, or GPRS Service.
Features:Package Includes:
- 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.
- The control interface of each pin description:
- GND – GND
