This module gives the Arduino board the possibility to communicate with the computer, laptop or even telephone via Bluetooth. The HC-06 module is already attached to the baseplate in this version, so that it can easily be connected to the Arduino.Bluetooth protocol: Bluetooth v2.0 + EDR (slave only) Frequency: 2.4GHz ISM band Modulation: GFSK (Gaussian Frequency Shift Keying) Send power: <= 4dBm, Class 2 Sensitivity: <= - 84dBm at 0.1% BER Speed: Asynchronous: 2.1 Mbps (Max) / 160 kbps Synchronous: 1Mbps / 1Mbps Security: Authentication and encryption Profiles: Bluetooth serial port Voltage: 3.3V - 6V (I / O at 3.3V) Flow: Mating - 35 mA, Connected - 8 mA Temperature: -40 ~ +105 degrees Baud rate: 4800, 9600, 19200, 38400, 57600, 115200, 230400, 460800, 921600, 1382400 https://elecena.pl/product/27739233/opencircuit-hc-06-bluetooth-module-met-adapter 2025-01-23 https://elecena.pl/product/27739233/opencircuit-hc-06-bluetooth-module-met-adapter 2026-04-11
