It’s a perfect tech for digital devices that don’t have a huge power pool to share their data conveniently. And this adapter is such a helpful little tool to turn any device with USB port into a Bluetooth armed cool device.
RB Bluetooth Transceiver, as a Bluetooth wireless communication module, is easy to use, lightweight and has high price value. Compared with the same products abroad, it is smaller but more powerful and special designed. Features are as follows:1, Sandwich plate design protect Bluetooth chip from being damaged by static electricity generated by users. 2, Wide power supply range: DC+3.3V/+5V~+12V and can be applied to various micro controller unit, Arduino, BS2 and other micro controllers. 3, LED indicator, switched on by micro DIP (ON for connect/OFF for power save mode), saves power. And clear Search(Power)/Connect indicator makes it easy to judge the working state. 4, Two lines of pin ports provide convenience to secondary development. Straight and bend pin headers and jumper cables can be mounted. It also can be applied to development board , controller, etc.
