Instruction

The computer debugs USB-TTL.The power supply of this module is: 5V-26V. If the 5V power supply must be above 2A, it is recommended that 9V power.After inserting the Arduino motherboard, the power supply must provide a current of 2A.The reason is that the GPRS Shield start -up current and the maximum peak of the work require the maximum of 2A, but the USB port cannot provide such a large current, so it must be connected to the power supply equipment.Another road supply port excrement leads 3.7---4.5V power supply is suitable for lithium battery power supply.Candidate is compatible with Arduino single -chip microcomputer.TTL serial compatibility is compatible with 3.3 and 5V microcontrollers.
Make sure your SIM card is not locked
GPRS SHIELD communication is best to communicate with 19200 BPS 8-N-1 (GPRS SHIELD default automatic pairing Potter rate)

Refer to the figure below

1. Provide 2 antenna interfaces, compatible with various needs.The shipment of this product has an antenna and an antenna rotation, so it is compatible with 2 interfaces.

2. SIM900 can be connected to any two pins from Arduino from D0 to D7 through the jump cap, not only the hardware UART of D0D1.

3. DEBUG dial the switch, you can set the DEBUG port of the SIM900 to Arduino or connect to the PC through the ATMEGA8U2/FT232 on the ARDUINO to perform debug debugging.

4. The audio and microphone outlet lead.

5. multiple IO ports of the SIM900, if necessary, can use DuPont to connect to the DuPont line -specific pin reference schematic diagram and DataSheet.

6. 3 status indicator and 3 buttons -the Power ON button in it can be Power on SIM900 by reaching the software by using Arduino's pin control.

7. 3.3V and 5V automatic level compatibility, can adapt to 3.3V or 5V main control board, supports other 3.3V platform development boards such as Leaf Maple and Chipkit.

The GPRS Shield is Based on Sim900 Module from Simcom and Compatition with Arduino and ITS Clones. The GPRS Shield PROVIDES You A Wayicate USING The GSM CELL Phone Network. The Shield Allows you to the achieve SMS, MMS, GPRS and Audio Via UART bySending at Commands (GSM 07.07, 07.05 and Simcom Enhanced at Commands). The shield also has the 12 gpios, 2 pwms and an adc of the simodulele (they are all 2V8 logic ) Present onboard.
