Product description

The Bluetooth Low Energy module enables wireless communication using the Bluetooth 4.0 standard, allowing it to communicate with modern smartphones, tablets, and other compatible devices. The module uses a dedicated low-power wireless protocol, making it possible to run battery-powered systems for extended periods.

The module is controlled via the serial UART interface and requires an operating voltage of 3.3 V. When connecting it to 5 V logic systems, a level shifter is required to prevent damage to the module. The integrated antenna provides reliable range for typical applications in homes or offices.

Example applications include remote controls for small robots or model vehicles, monitoring sensor data on mobile devices, wearable devices with wireless access to external data sources, and communication between prototypes without cables. Its low power consumption makes the module especially suitable for battery-powered applications where long operating times are important.

No additional accessories are required for operation apart from a power supply and connecting wires. The module is configured using AT commands via the serial interface. Check the circuit diagrams beforehand to avoid confusion about voltage levels.

Safety notice

This module is intended exclusively for building prototypes and for testing and development purposes. It is not suitable for installation in household mains circuits. Ensure the power supply polarity and voltage levels are correct when connecting the module to other components. If in doubt, consult a qualified electrician before use.
