HC-05 Wireless Bluetooth Serial Pass-Through Module for Arduino - Green
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.
Specification
l Sensitivity (Bit error rate) can reach -80dBm,The change range of output’s power: -4 - +6dBm.
l Has an EDR module; and the change range of modulation depth: 2Mbps - 3Mbps.
l Has a build-in 2.4GHz antenna; user needn’t test antenna.
l Has the external 8Mbit FLASH
l Can work at the low voltage (3.1V~4.2V). The current in pairing is in the range of 30~40mA.
l PIO control can be switched.
l This module can be used in the SMD.
l It’s made through RoHS process.
l The board PIN is half hole size.
l Has a 2.4GHz digital wireless transceiver.
l Bases at CSR BC04 Bluetooth technology.
l Has the function of adaptive frequency hopping.
l Small (27mm×13mm×2mm)
l Peripherals circuit is simple.
l It’s at the Bluetooth class 2 power level.
l Storage temperature range: -40 ℃ - 85℃,work temperature range: -25 ℃ - +75℃
l Any wave inter Interference: 2.4MHz,the power of emitting: 3 dBm.
l 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.
