Product Description :

The SPP-C Bluetooth module offers a robust and user-friendly approach to wireless data transmission. Based on the JL AC692X series chip, it is pre-configured to create a seamless, transparent wireless UART channel. Any data sent to its UART interface is automatically transmitted via Bluetooth to a paired device, and vice-versa, functioning exactly like a wireless serial cable.

The module is designed for simple integration, operating at 3.3V logic levels and supporting a wide range of configurable baud rates. Its compact size and low power consumption make it suitable for various applications, from DIY electronics to commercial products. The SPP-C is typically used as a slave device, waiting for a connection from a master like a smartphone or PC, but it can also be configured as a master to initiate connections to other slave devices.

Key Features :

• Dual Mode Operation: Can be configured as either a Master or a Slave device.

• Transparent Data Transmission: Creates a seamless wireless UART bridge with no protocol overhead.

• Simple AT Command Configuration: Easy setup of parameters like name, baud rate, and PIN via serial commands.

• Compact Form Factor: Small size for easy integration into space-constrained designs.

• Integrated Antenna: Built-in PCB antenna for a complete solution without external components.

• Wide Voltage Compatibility: Supports a common 3.3V operating voltage.

• Auto-Connection Feature: Can be set to automatically reconnect to a paired device on power-up.

Applications :

The SPP-C module is perfectly suited for a variety of wireless data transfer applications, including:

• Wireless Communication for Arduino, ESP8266, and other Microcontrollers

• Bluetooth-enabled DIY Robotics and RC Models

• Wireless Data Logging from Sensors

• Cable Replacement for Industrial Serial Devices

• Wireless Configuration and Debugging Interfaces

• Simple Home Automation and Control Systems
