Bluetooth 2.0 Module V3 For Arduino

The DF-Bluetooth V3 Bluetooth module is designed with a unique double-board construction that not only enhances its aesthetic appeal but also serves as a shield against electrostatic damage. It supports two DC power inputs, accepting a broad voltage range from 3.5V to 8V, as well as a 3.3V power supply, which makes it versatile for different deployment scenarios.

Status updates are easily monitored with a clear, bright LED indicator. The LED depicts both module status and connection status, utilizing distinct flashing patterns to indicate search and connection states. The on-board antenna is engineered to deliver high-quality signals, ensuring reliable connectivity.

For easy control, a DIP switch is included to manage the module’s settings. Users can turn off the LINK light to activate power saving mode or switch to AT Mode for configuring the baud rate and toggling between master and slave modes via AT commands. The module is versatile in functionality, allowing it to form paired connections for transparent serial data communication.

Compatibility is a key feature of the DF-Bluetooth V3 module. Extensive testing has confirmed its compatibility with most Bluetooth adapters on the market, including Bluetooth dongles, laptops, and mobile phones. This ensures seamless integration, even with Android devices, further broadening its usability across platforms.
