Serial Bluetooth RF Transceiver Module RS232 w/ Backplane Enable & State Pin

Serial Bluetooth RF Transceiver Module RS232 w/ Backplane Enable & State Pin

This small size Bluetooth TTL transceiver module allows your target device to both send or receive the TTL data via Bluetooth technology without connecting a serial cable to your computer. It's easy to use and completely encapsulated.

Features:
- TTL data transparent transfer between a host Bluetooth device.
- Works with any USB Bluetooth adapters.
- Default Baud Rate: 9600,8,1,n.
- Coverage up to 30ft.
- Built in antenna.
- Power input: +3.3VDC.
- Mini Size.

Others:
- TXD: Transmit Data (Data output pin for the UART),must be connect to the RXD of you device
- RXD: Receive Data (Data input pin for the UART),must be connect to the TXD of you device
- VCC,GND: power supply,between 3.6V~6.0V,Prohibit more than 7V,Otherwise, damage to device!
- State: Connection status output,when bluetooth is connect,output high,otherwise,output pulse(about 5Hz)
- ON/OFF: Power Control,when is low(default),power is open,when is high(not less than VCC-0.5V),power is close
