Arduino经常预算的蓝牙耳机的无线电收发器

RB Bluetooth TransceiverIntroductionRB 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.Compatible with many bluetooth adapters Specifications 1, Bluetooth: CSR BC417143 2, Bluetooth Protocol Specification: Bluetooth Specification v2.0+EDR 3, Transmission frequency: 2.4 2.48GHz unlicensed ISM band 4, USB protocol: USB v1.1/2.0 5, Modulation system: GFSK(Gaussian Frequency Shift Keying) 6, Transmission power: ≤4dBm, Class 2 7, Transmission distance: 20 30m in free space 8, Receiving sensitivity: ≤-84dBm at 0.1% BER 9, Transmission rate: Asynchronous: 2.1Mbps(Max) / 160 kbps;Synchronous: 1Mbps/1Mbps 10, Security feature: Authentication and encryption 11, Support profiles:Bluetooth serial port 12, Serial port default setting: 115200/N/ 8/1 13, LED indicator: Search(Power)/Connect 14, Input power: +5V +12VDC/+3.3VDC 50mA 15, Working temperature: –20°C +55°C 16, Dimensions: 30mm x 30mm 17, Weight: 67gSandwich plate design,protect chip from static damageBiserial pins,hommization designThicken gold-plate board,selected materialAbundant supplyApplication videos(Copy link into browser)RB bluetoothusing methodhttp://v.youku.com/v_show/id_XNzY2NjI0MzY=.html
