DFRobot Bluetooth V3

Description

The DF-BluetoothV3 module uses a unique "double card" design, which is exceptional for preventing any damage to the data module from excess electrostatic energy. It is designed to have two DC power inputs, a wide voltage capacity (3.5V ~8V) and 3.3V for the power supply. It has a built-in antenna on the board that guarantees a high quality signal. The DIP Switch allows you to set the status of the module, LED Off to enter energy saving and AT Mode to allow the module to access AT command mode. This module has been tested and is compatible with most bluetooth adapters on the market, and is compatible with Android phones.
