SIM900A module development board GPRS STM32 GSM wireless data DTMF for arduino
NOTE: You need to know the way to use before ordering it.
UNV-SIM900A-V3.8.2 development board introduced
Power supply requirements: 5V power supply, the current need to provide 1.5A or more;
TTL level serial compatible 3.3V and 5V microcontroller. Real can be directly related to 51/STM32/MP430 and other microcontroller;
In the early use of computer debugging, it is recommended to use the USB-TTL CP2102 module to power and communication module;
When using single chip microcomputer control module, but also through the USB–232 monitoring module to return the data to the instruction, which greatly facilitates to find the problem, especially suitable for small partners with 51 mcu.
Standby in the 40MA or so, you can set the sleep state in the low power consumption of about 10MA.
Support SMS, GPRS data transmission, sending MMS, DTMF, HTTP, FTP, PPP dial-up function.
At the same time, the hardware contains a reset pin. When problems arise, the module can be used to solve this problem.
Development board supports 2G/3G/4G Unicom or mobile phone card.
