JDY-31 Bluetooth 3.0 SPP Module HC-05 HC-06 Compatible

The JDY-31 Bluetooth 3.0 SPP Module is a highly efficient, cost-effective wireless serial data transmission module designed for seamless device-to-device communication. Powered by the high-performance BK3231S chip, this module operates on the classic Bluetooth 3.0 SPP (Serial Port Profile) standard. It serves as an excellent, budget-friendly drop-in replacement for traditional HC-05 and HC-06 slave modules, allowing makers and engineers to upgrade their wireless projects without modifying existing circuit layouts.

This module is highly compatible with Android and Windows operating systems, making it perfect for smart home automation, robotics, wireless data logging, and DIY microcontroller projects. With its standard UART interface, it easily connects to popular development boards like Arduino, ESP32, STM32, and Raspberry Pi. The compact stamp-hole (castellated) design allows for both direct SMD mounting on custom PCBs or soldering standard 2.54mm pin headers for breadboard prototyping.

Features:

• High Compatibility: Fully compatible with HC-05 and HC-06 slave module protocols and pin configurations.
• Bluetooth 3.0 SPP: Supports classic Serial Port Profile for fast and reliable wireless data transmission.
• BK3231S Core Chip: Equipped with a robust Beken BK3231S controller and a 16.000 MHz crystal oscillator for stable RF performance.
• Onboard PCB Antenna: Features a built-in high-gain PCB antenna, eliminating the need for an external antenna.
• AT Command Configurable: Easily customize the device name, baud rate, and pairing PIN using standard AT commands via UART.
• Compact Form Factor: Castellated edge design allows for easy integration into commercial PCB designs and DIY projects alike.
