## Description

BT06 Bluetooth module for Arduino and other boards, quickly creates a wireless SPP serial connection for short-distance data exchange between PC, phone or equipment. Easily integrates via UART, has sensitive transceiver for stable links, low power and cost, plus integrated PCB antenna. Power supply 3.6-6V, logic 3.3V.
Bluetooth Module BT06, compatible with Arduino and other development boards.
The module supports UART interface and the serial port protocol SPP. Its advantages are small size, cost, and high sensitivity of the transceiver.
IMPORTANT: The module does NOT tolerate logic voltages higher than 3.3V. This is especially true for the RX pin of the module. Use a level converter or voltage divider using resistors to reduce the voltage to 3.3V if necessary.
