JDY-08 Motherboard Module

Product Introduction:

The JDY-08 transparent transmission module is based on the Bluetooth 4.0 protocol standard, with a working frequency range of 2.4GHz, modulation method of GFSK, transmission power of 0dB, transmission distance of 80 meters, and adopts the TICC2541 chip design. It supports users to modify device names, service UUID, transmission power, pairing codes and other instructions through AT commands, making it convenient, fast, and flexible to use.

Function Introduction:

1: WeChat transparent transmission (supporting AirSync protocol, applied to WeChat H5 or manufacturer server communication, including long packet data parsing and transmission)

2: APP transparent transmission (supports Android and IOS data transparent transmission)

3: IBeacon mode (supports WeChat Shake One Shake Protocol and Apple iBeacon Protocol)

4: Sensor mode (temperature, humidity, and many other sensor data collection applications)

5: Host transparent transmission mode (data transparent transmission between application modules, communication between host and slave)

6: Host observer mode (application sensors, indoor positioning)

7: PWM mode (applied to motor speed regulation and LED light brightness adjustment)

8: IO mode (applied to mobile phone control relays or LED on/off)

9: Indoor room positioning application (using iBeacon data collection to achieve range positioning)

Technical parameters:

1: Communication rate 3K bytes/second

2: When the APP is transparent, the serial port supports writing 1024 bytes

3: Effective communication distance of 15 to 30 meters

4: Support PWRC pin control for sleep

5: Support IO port control for disconnection

Pin Function Description:

DISC pin: used to actively disconnect Bluetooth connection (default high-level, low-level disconnection)

PWRC pin: used to wake up sleep (default to sleep state). During use, this pin can only be grounded to issue AT commands

VCC pin: It is the power pin of the module, with a power supply voltage range of 3.6V to 6V

GND pin: power ground

TXD pin: Serial output pin

RXD pin: Serial input pin
