SIM900A GSM GPRS Wireless Extension Module With Antenna-V4.0

This module power requirement 5VPower supply initial commissioning computercomputerUSB poweredMeet the requirements. Because we added a large capacitance 1000UF.Recommended time data transmission over large electricity 1A DC, TTL level serial port compatible adaptive 3.3V, and 5V microcontroller. It can be directly connected to the microcontroller. Standby around 80MA, you may be disposed about the sleep state 10MA low power consumption. Computer debugging USB Ð 232 and USB Ð TTL can, according to their accessories may be. Support SMS, data, multimedia, Internet, and so on. Reset pin lead, maybe implemented on-site unattended remote reset with function DTMF remote control function. The biggest advantage is the retention module 232, in learning or development can monitor the implementation of the 51 low-end microcontroller module and instruction to more quickly identify the cause, saving development time, and learning.
