Bluetooth SPP Serial Port Transparent Transmission Module TTL to Bluetooth

Description

Bluetooth SPP Serial Port Transparent Transmission Module TTL to Bluetooth

This UGE Bluetooth module functions similarly to the HC-06 module, providing SPP (Serial Port Profile) communication for wireless UART transmission. It allows microcontrollers (like Arduino, ESP32, STM32, etc.) to communicate with PCs, smartphones, or other Bluetooth devices using serial commands over Bluetooth.

 Specifications:

• Bluetooth Version: Bluetooth 2.0 + EDR (SPP)
• Communication Mode: Transparent Serial UART
• Baud Rate (Default): 115200 bps
• UART Interface: 5V TTL Logic (TX/RX)
• Data Bits: 8
• Stop Bit: 1
• Parity: None
• Range: Up to 10 meters (Class 2)
• Operating Voltage: 5V
• Current Consumption: ≤ 40mA
• Connection Status Indicator: LED (blinks when not paired, stays solid when connected)
• Operating Temperature: -25°C to +75°C
• Wireless Communication Speed: Up to 1 Mbps
• Compatible with: Android, Windows, Linux, macOS (SPP-compatible devices)

 Pinout:

 Applications:

– Wireless Serial Communication between Arduino, ESP8266, ESP32, Raspberry Pi, STM32, etc.
– Robotics & Remote Control Systems – Control devices via Bluetooth from a smartphone or PC
– Wireless Debugging & Data Logging – Send/receive serial data without wires
– Industrial Automation – Replace wired UART communication in embedded systems
– Smart Home & IoT – Bluetooth-based device control

 Example Usage with Arduino

 Conclusion

This self-made Bluetooth SPP serial module is a reliable, easy-to-use wireless UART solution, ideal for Arduino, ESP8266, STM32, Raspberry Pi, and other microcontrollers. If it works like an HC-06, it should support AT commands for configuration and 5V logic compatibility for seamless integration.
