Product details

The power supply requirements of this module: 5V power supply, the computer USB power supply can meet the requirements in the early of computer debugging. Because we added a capacitor of 1000UF. For long-term data transmission, it is recommended to use a DC power of more than 1A, and the TTL level serial port is adaptively compatible with 3.3V and 5V microcontrollers.
Can be directly connected to the microcontroller. The standby time is about 80MA, and the sleep state can be set to be low power consumption at about 10MA.
The computer can debug USB--232 and USB--TTL, depending on the accessories of each person. Support SMS, data, , Internet access, etc. The reset pin header can realize unattended remote reset on site, and realize remote control function with DTMF function.
The biggest advantage of the module is to reserve 232 ports. When learning or developing, you can monitor the execution of 51 low-end microcontrollers and module instructions, and you can find out the reasons faster.
Serial port circuit: and magnetic bead protection devices are used to the board, so that the board will not be damaged by surge and high voltage. circuit: SMF05C electrostatic discharge chip.
Antenna circuit: keep it short and straight, so as to signal strength.
PCB display: Each interface is marked by silk screen, which is convenient for secondary development. The design completely follows the SIM900A hardware design .
All the way 5V power supply interface: We have made protection, even if it is reversed, it will not burn the board. In the early of the computer debugging, the USB power supply of the computer can be used; the power consumption for long-term data transmission is , and we recommend DC above 1A.
One TTL interface: support 3.3V microcontroller and 5V microcontroller. That is to say, it supports 51 types of 5V microcontrollers and STM32 microcontrollers.
Two-way antenna interface: SMA antenna interface, IPX MINI antenna interface (not welded by default).
One 232 level interface: that is to say, you can directly connect the module to the computer through a 232---USB serial cable. Can also be connected to a computer via USB--TTL
