The Bluetooth module includes a set of PCB-A designed for use with the Bluetooth chip as the core product. The versions of the Bluetooth module are 1.0, 2.0, 3.0, 4.0, 4.2 and even the current 5.0. Our Bluetooth module has industrial design, stable data transmission, simple operation and cost advantages, and can be widely used in the field of wired (serial) to wireless data transmission. Our Bluetooth module can be paired and connected with all Android phones, notebooks, computers and Bluetooth main modules with Bluetooth function, so as to send and receive data in both directions.
The module itself has three main features: its own MP3 function (TF card or U disk can be connected), mobile phone Bluetooth communication, UART serial port control.
