SIM800A mini board with high-performance industrial grade GSM / GPRS module: SIM800A, working frequency band: GSM900 / 1800MHz. Can achieve telephone voice, SMS (SMS, MMS), GPRS data transmission function (Support transparent mode, domain name resolution and IP mode), Also hasDTMF decoding(You can identify the other button),TTS(OptionalLocal voice broadcast) and Bluetooth (Optional). Hardware design in the official design to be optimized, the use of efficient switching power supply, SIM card using the mainstream MICRO deck, more solid quality.

Module applications: remote monitoring, remote intelligent meter reading, intelligent home and automotive equipment and other remote communications equipment.

Module Features:

Wide voltage supply:5 ~ 18V DC power supply, Flexible to adapt to different power supply voltage system, GPRS module power supply is characterized by low voltage, peak current, so the higher the development board power supply voltage, the smaller the current, the smaller the power pressure.

Power on automatically:Power on without a button or microcontroller control boot, easy to operate, simple.

Power control:The module power supply is available Power control pin control, high power supply, low powerThe Power consumption module close to 0, when the module can crash through the program control module restart, no need to restart the machine power, the default pin is high, do not have to be vacant.

Serial TTL and RS232:The module can be easily connected to various microcontrollers or other serial devices via serial TTL or RS232 level control.

audio port:The audio input and audio output connectors are pinpointed for flexible use by the user.

TTS and Bluetooth functions: The default does not have this feature, the need for the function needs to inform in advance.
