Bluetooth Module HC-05 features

  • HC05 follows the “Bluetooth V2.0+EDR” protocol (EDR stands for Enhanced Data Rate).
  • Its operating frequency is 2.4 GHz ISM Band.
  • HC05 uses CSR Bluecore 04-External single-chip Bluetooth system with CMOS technology.
  • This module follows the IEEE (Institute of Electrical and Electronics Engineers) 802.15.1 standard protocol.
  • Dimensions of HC-05 are 12.7mmx27mm.
  • Its operating voltage is 5V.
  • It sends and receives data by UART, which is also used for setting the baud rate.
  • it has -80dBm sensitivity.
  • This module also uses (FHSS), a technique by which a radio signal is sent at different frequency levels.
  • This module has the ability to work as a master/slave mode.
