It operates in slave mode and receives connection requests from external devices. The module uses the host system's standard UART interface (serial interface) and translates the data into the Bluetooth protocol.\u003c\/p\u003e \u003cp\u003eThe module is powered by 3.3 to 6 V and draws approximately 20 mA during active operation. Since it operates as a slave, it must first pair with a master Bluetooth device. A typical setup connects it to a smartphone or tablet, which uses the module as a serial interface through an app. The data rate is factory-set to 9600 baud and can be adjusted as needed.\u003c\/p\u003e \u003cp\u003eUnder ideal conditions, the range is 10 to 100 meters and depends on the environment, antenna design, and receiver. The module is suitable for applications such as smartphone-controlled remote robots, wireless sensor readout, wireless data loggers, or remote monitoring of simple devices using mobile devices. In practice, the connection proves reliable once paired.\u003c\/p\u003e \u003cp\u003eYou need at least a microcontroller with an available UART interface or a compatible board onto which the module can be soldered or plugged in. If the host uses 5 V logic, a level shifter is required between TX and RX to ensure the module's 3.3 V outputs are detected correctly. Configuration is done using AT commands and can still be adjusted after installation.\u003c\/p\u003e \u003ch3\u003eSafety Information\u003c\/h3\u003e \u003cp\u003eThe module is not intended for direct connection to the mains. It is intended exclusively for building prototypes and for testing and development purposes. Work on or immediately next to an electrical installation must be carried out by a qualified electrician; if in doubt, contact a qualified electrician before putting the module into operation.\u003c\/p\u003e","brand":"Funduino","offers":[{"title":"Default Title","offer_id":65998305558877,"sku":"F23106816","price":7.75,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1074\/5649\/5965\/files\/bluetooth-modul-typ-hc-06-funduino-5346853.png?v=1791495502","url":"https:\/\/funduino.com\/en\/products\/bluetooth-module-type-hc-06","provider":"Funduino","version":"1.0","type":"link"}
