HC-06 Bluetooth Module

This HC-06 Bluetooth module connects an Arduino to an Android phone, laptop or tablet. The module provides a serial connection via Bluetooth 2.0 (SPP) and works only as a slave, so it waits for the connection from the other device. It is not compatible with iPhone and iPad.

Recommended alternative with Bluetooth 4.0 (BLE), for example for iPhone: Beetle Bluno BLE smallest Arduino with Bluetooth 4.0

Recommended Accessories:

• Dupont Cable M-F 20cm 20 Pieces
• Logic Level Converter 2-Channel 5V / 3.3V

Features:

• VCC to +5 V, RX is designed for 3.3 V (marked LEVEL: 3.3V)
• On a 5 V board, a level shifter or voltage divider belongs between the board's TX and the module's RX
• The module's TX can usually be connected directly to the Arduino's RX
• AT commands only work while there is no Bluetooth connection
• The default is 9600 baud and PIN 1234; depending on the firmware also 38400 baud, if in doubt test both values

Application Examples:

• Controlling an Arduino from a phone
• Sending measured values to a laptop or tablet
• Remote control of robots and vehicles
