Key item features

Versatile Modes: Functions as both a master and slave device, allowing connections to phones/computers or initiating links between other Bluetooth modules like Arduinos.
Transparent Serial: Acts as a wireless UART replacement, facilitating transparent serial data transfer without requiring complex Bluetooth protocol knowledge.
Configurable Settings: Utilizes AT commands at 38400 baud to customize device name, pairing password, baud rate, and master/slave role.
Power Compatibility: Operates on 3.6V to 6V input with an integrated 3.3V regulator, but requires a voltage divider for the RX pin when connecting to 5V Arduino.
Wireless Range: Provides up to 10 meters (30 feet) line-of-sight wireless range using Class 2 Bluetooth and a built-in PCB antenna.
Efficient Power: Consumes approximately 30 mA when searching or unpaired and only 10 mA when actively connected, suitable for battery-powered applications.
Broad Compatibility: Works with Android phones/tablets, Windows, and Linux computers, but is incompatible with iOS devices due to lack of Bluetooth Classic SPP support.
