## Description

Bluetooth module for RS232 serial communication, compatible with Arduino and other development boards, ideal for transmitting and receiving wireless data and remote control from your phone. It works in Slave mode, has 3.3-6VDC power supply with 3.3V logic, coverage up to 10 m and Bluetooth 2.0 + EDR, with default baudrate 9600.
The HC 06 RS232 Bluetooth module is compatible with development boards such as Arduino, ideal for wireless transmission and reception of information via Bluetooth.
You can use this module to remotely control any kind of project through your mobile phone.
Important: The Arduino RX pin works with both 5V logic voltage and 3.3V. The RX pin of the HC-05 module DOES NOT tolerate 5V logic voltage. Use a level converter or a voltage divider with 1k and 2k resistors. Resistors with higher values will prevent fast data transmission.
