Description
This module power supply: 5VPower supply, initial commissioning computer computerUSB poweredMeet the requirements. Because we added a large capacity of 1000UF of it. 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 can be drained about the sleep state 10MA low power consumption. Computer debugging USB-232 and USB-TTL can be, according to their accessories can be. support SMS, data, multimedia, Internet and so on. Reset pin lead, can be implemented on-site unattended remote reset with function DTMF remote control function. the biggest advantage is the retention module 232, In learning or development, the implementation of the 51 low-end microcontroller module and instruction can be more rapid in the cause, saving development time and learning. [Support 2,3,4G phone card].

Features
Serial port circuit: Support 3.3V microcontroller.
TTL serial port: Supports 3.3V and 5V microcontrollers.
SIM card circuit: Added SMF05C ESD chip.
Antenna circuit: ensure short and straight, thus ensuring signal strength.
PCB display printing mark: Each interface is easy to develop twice, and the SIM900 / A hardware is completely designed according to the design manual.
Two power interfaces: VCC5, 1A above 5A DC. The computer 5V power supply can use the computer USB early. The DC long data circuit exceeds the recommended 5V1A. VCC4, 4.8-5.2V power supply, same as above, suitable for lithium batteries.
