DollaTek 3Pcs Wireless Bluetooth Transceiver Modul Slave and Master with 6 set cable for Arduino

• Bluetooth module Master and slave Two in one module
• Use the CSR mainstream bluetooth chip, bluetooth V2.0 protocol standards
• Module working voltage 3.3 V
• Coupled Mode: Two modules will establish communication automatically when powered. PC hosted mode: Pair the module with bluetooth dongle directly as virtual serial.
• Note: This is not original Arduino product. it only a substitute accessories from DollaTek

Product specifications: 1. PCB dimensions: 37.3 mm (length) x 15.5 mm (W). 2. Weight: 3.5 g 3. Input voltage: 3.6V-6V, 7V prohibit via 4. Power anti-reverse, reverse module does not work. 5. Lead to 6 pin: EN / VCC / GND / RXD / TXD / STATE (Bluetooth status leads to the foot, is not connected to the output low, output high after connection). 6. When status indicator, LED flash means that there is no Bluetooth connection. Slow LED flash points into AT command mode 7. On-board 3.3V controller chip, the input voltage DC 3.6V-6V; in unpaired state, the current is approx. 30mA (as the LED flashes and the current change state changes). After successful coupling, the current is approx. 10 mA. 8. Level interface 3.3V, you can directly connect a variety of microcontrollers (Arduino / 51 / AVR / PIC / ARM / MSP430 etc.) directly, 5V microcontrollers can also be connected directly. Connected directly to the serial port of the microcontroller, you cannot go via the MAX232 chip! 9. The effective transmission distance in the open area of 10 metres over 10 metres is possible, but does not the quality of the connection. 10. Can be used as a full-duplex serial interface after successful pairing. You don't need to know Bluetooth protocol, only support 8 data bits, 1 stop bit and no parity communication format. This is the most commonly used communication format and does not support any other format! 11. Press the button to turn on the Bluetooth module. You can switch to AT mode, set parameters and query information 12. You can switch between master and slave mode via AT commands Package includes: 3 x WINGONEER Bluetooth module. 3 x Dupont cable
