HC-05 HC-06 HC-04 bluetooth module price


 Feature
  Wireless transceiver
    Sensitivity (Bit error rate) can reach -80dBm.  
    The change range of output’s power:    -4 - +6dBm.  
  Function description (perfect Bluetooth solution)

Has an EDR module; and the change range of modulation depth: 2Mbps - 3Mbps.
Has a build-in 2.4GHz antenna; user needn’t test antenna.
Has the external 8Mbit FLASH
Can work at the low voltage (3.1V~4.2V). The cu rrent during pairing will fluctuate at the range
of 30～40mA. The current during communication is 8mA.    
Standard HCI Port (UART or USB)
USB Protocol: Full Speed USB1.1, Compliant With 2.0
This module can be used in the SMD.
It’s made through RoHS process.
The board PIN is half hole size.

  Has a 2.4GHz digital wireless transceiver.
  Bases at CSR BC04 Bluetooth technology.  
  Has the function of adaptive frequency hopping.
  Small (27mm*13mm*2mm)
  Peripherals circuit is simple.  
  It’s at the Bluetooth class 2 power level.
  Storage temperature range: -40  ℃ - 85 ℃, work temperature range: -25  ℃ - +75 ℃
  Any wave inter Interference: 2.4MHz，the power of emitting: 3 dBm.
  Bit error rate: 0. Only when the signal decays at the transmission link, bit error may be
produced. For example, when RS232 or TTL is being processed, some signals may decay.  
  Low power consumption
  Has high-performance wireless transceiver system
  Low Cost
