The stock we have is registered to the indo network before april 18th., And we 've tried to work after imei' s blocker rule came into effect.,
The sim900a mini module is compact and low- cost, yet still has good performance. The circuit is designed for the sim900a 's basic pins, which integrate conventional slot sizes and antennas. The sim900a is designed for direct 5v power supply and requests no large currents (# thanks to diodes and capacitors #)Which can be supplied directly from the arduino 5v or from the computer usb port, the gipo pins. The sim900a can also communicate directly at a logic level of 3-5vdc.
Note that if you want to use this circuit for the project, Running long and stable should be powered from 3a or more, In addition to the gpio pins of the sim900a with microcontroller should be through the buffer ic or serial connection (About 1k) To limit the line
Specifications.
Power supply: 4.5-5v, can be used with low current source 500mah or more (such as usb port, source from arduino board). Recommend 2a to ensure the performance of the sim
Line when standby: 10 ma
Flow when operating: 100 ma to 2a.
Size: 2.5cm x 3.1cm
Functional pins
Vcc: Input to 5v.
Uart transmitter tx.
Rxd: Uart rx receiver.
Headphone: Beep sound.
Mic: Receiver foot (must attach micro gnd to this leg to get the sound).
Mass feet, 0v l
