SIM900A MINI Wireless Data Transmission Module GSM GPRS Development Board Kit w/ Antenna

SIM900A MINI Wireless Data Transmission Module GSM GPRS Development Board Kit w/ Antenna

Description:
- Board is suitable for the development (commonly known as development board) before the study, but also directly embedded into your equipment, engineering (already have a lot of cases)
- The advantages of the board
- Serial interface circuit: the TVS and magnetic beads protection device to protect the board, the board will not surge, high voltage damage.
- SIM card circuit increase SMF05C chip electrostatic discharge.
- Antenna circuit: the door type circuit, it can be finished in a PCB printing after 50 ohm matching design, at the same time ensure short and straight, so as to ensure the signal strength.
- PCB show: each interface screen printing mark, convenient for secondary development, the design fully follow SIM900A hardware design manual.
