Generic Hc-05 Bluetooth Serial Pass Through Module Wireless Serial Communication From Machine Wireless Hc05 for Arduino

HC05 module is an easy to use Bluetooth SPP (Serial Port Protocol) module, designed for transparent wireless serial connection setup.
Serial port Bluetooth module is fully qualified Bluetooth V2.0+EDR (Enhanced Data Rate) 3Mbps Modulation with complete 2.4GHz radio transceiver and baseband. It uses CSR Bluecore BC417143 chip. It has the footprint as small as 12.7mmx27mm. Hope it will simplify your overall design/development cycle.
Sensitivity (Bit error rate) can reach -80dBm,The change range of output's power: -4 - +6dBm.
HC-05 is made through RoHS process. It has an EDR module; and the change range of modulation depth: 2Mbps - 3Mbps. It an work at the low voltage (3.1V~4.2V). The current in pairing is in the range of 30~40mA.
The storage temperature range: -40 ℃ - 85℃,work temperature range: -25 ℃ - +75℃. Bit error rate: 0. Only 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.
It bases at CSR BC04 Bluetooth technology.It has the function of adaptive frequency hopping.
