JDY-31 SPP-C Bluetooth Module - Replacement for HC-05 / HC-06 - Arduino

Bluetooth SPP-C module is a replacement for HC-05/06 modules. Universal Bluetooth communication module for Arduino, APM, AlexMos and MultiWifi, based on BEKEN BK3432 chip. The system works on the ARM968E-S processor, has 128KB of Flash memory, a built-in temperature sensor, and many different interfaces, such as: PWM, ADC, UART, I2C, SPI, GPIO, WDT, Timer.

The module allows you to connect any device with a phone, smartphone, tablet or other device wirelessly.

Product features

Standardized Bluetooth technology eliminates the problem of drivers and compatibility. The modules allow for communication up to 10m.
Serial communication through the UART port (pins RX, TX) - with a signal voltage of 3.3 V
Attention to the voltage of UART signals (pins RX, TX) (cannot be 5V) (use a voltage divider or a voltage converter when connecting to Arduino)
The module has soldered Goldpin headers that allow you to connect the module to the breadboard or connect using wires, jumpers, DuPont cables.
Transparent data transmission function - can be used with other devices

Starting the module

In order to start the module, connect supply voltage to the pin marked VCC.
The module will be detected by the computer as unknown chip or HC-06
To pair both devices, enter the password: 1234.
A virtual COM port will appear in the system, through which data can be sent using any terminal.

You can connect to the module:

Arduino boards - attention to the voltage of UART signals (cannot be 5V) (you can connect the Arduino Uno and others through a converter)
MultiWii controllers
APM controllers
AlexMos Gimbal Controllers
