HC-05 Bluetooth Module

• This module can be configured in a transmitter or receiver, the transmitter could be paired with the receiver, the receiver and the receiver or the transmitter and the transmitter can not communicate between when buying, the default value for the receiver.
• It uses the conventional Bluetooth chip CSR, Bluetooth V2.0 protocol standards.
• 3.3 V operating voltage module
• Potter default rate of 9600, the user can be set.
• Core module size: 28mm x 15mm x 2.35mm.
• Operating current: compatible with 30 MA, which coincides with 8 MA communication.
• Current of rest: without rest.
• Used for GPS navigation system, water meter and electricity meter reading system.
• With computer and Bluetooth adapter, PDA, seamless connection equipment
• Business series: series of Bluetooth modules
• With LED indicator light, uses 3.3 mA and V. regulation chip
• With VCC. GND. TXD. RXD foot for Bluetooth
• With "Re-SEARCH" button (on / off / activation foot for it, external MCU outside / "high level" input can control the module to search again)
• Compatible with Bluetooth master module "Slave module" or Slave master module (integer).
• Input voltage: 3.3-6 V
• Size: 1.55 cm * 3.98 cm
• Input power supply 3.3 6 V, prohibition more than 7 V
• It does not "automatically prevent the operation of the power supply", so it correctly connects the power supply
• We recommend installing "Bluetooth master module"
• The "status" is the output foot for the status of the LED, When Bluetooth "not connected", it emits "Pulse", When Bluetooth "connected", emits "high level", we can determine the States from "MCU"
• If only the card, There is no "Bluetooth function"
