Warm  Prompt :

We promise to use brand new original chips for the Bluetooth module. There are many low-cost counterfeit and high imitation on the market. There is no problem in the first use, but long-term use will cause problems such as unstable performance, which will eventually lead to unusable.

HC-06 :

• Bluetooth protocol: Bluetooth 2.1+ EDR standard

• USB protocol: USB v1.1/2.0

• Operating frequency: 2.4GHz ISM frequency band

• Modulation mode: Gauss frequency Shift Keying

• Transmit power: ≤ 4dBm, second stage

• Sensitivity: ≤-84dBm at 0.1% Bit Error Rate

• Transmission speed: 2.1Mbps(Max)/160 kbps (Asynchronous)； 1Mbps/1Mbps (Synchronous)

• Safety feature: Authentication and encryption

• Supported configuration: Bluetooth serial port (major and minor)

• Supply Voltage: 5 V DC 50mA

• Operating temperature: -20 to 55℃

HC-05 :

• 1. core module uses HC-05 slave module, pins include VCC, GND, TXD, RXD, KEY, Bluetooth state pin (STATE), output low if not connected, high if connected

• 2. LED indicates the connection status of Bluetooth, quick flash means no connectivity, slow flash means entering AT mode, double flash means Bluetooth is connected and the port is open.

• 3. BOttom plate has anti-reverse diode,with 3.3V LDO. input volt is 3.6~6V; current about 30mA with no pairing, current about 10mA after pairing. Input volt should be within 7V!

• 4. Pin level is 3.3V. It can be directly connected with various MCUs (51, AVR, PIC, ARM, MSP43 etc.) , also 5V MCUs, no need for MAX232 and cannot be connected with MAX232!

• 5. In open area, effective range is 10m (power level is CLASS 2). It’s possible to be more than 10m. But the connecting quality cannot be guaranteed.

• 6. After paring , it can be used as full duplex serial port. No need for knowing any Bluetooth protocol. It supports 8-bit data bits, 1 stop bit; can set odd-even check communication format, which is the most common communication format; do not support other formats.

• 7. Can access AT command to set parameters, and query information by pulling high pin 34.

• 8. Small size (3.57cm*1.52cm), SMD production, ensure quality; with transparent heat shrinkable film for dustproof and anti-static function.

• 9. Use AT-command to switch from master or slave mode, and to connect to specific devices.

• 10. Support standard baud rate of 4800bps~1382400bps.
