HS0285 SIM808 development board alternative for 908
Original design, the interface will not be commonly used (Bluetooth, USB) on the back, greatly saving PCB space.
2 power control pins are forced to pull high, to prevent the interference will lose the power supply module.
Three 3 positioning holes can be perfectly installed and positioned, and the installation process is reduced by 25%.
4 we provide the latest program, the latest design, peer not, because they are copying our.
5 our products sell well at home and abroad, the product is stable, and many times to get the international friends of the project orders.
