An evaluation board for a dual-mode Bluetooth 5.0 module that handles both wireless audio and serial data pass-through simultaneously. It can play audio from U-disk or TF card, stream audio over Bluetooth, handle Bluetooth call control, and run BLE or SPP data pass-through — all at the same time, with simple UART serial control.
The dual-mode design significantly reduces the development complexity of embedding Bluetooth audio and data connectivity into a single product.

Jargon buster
Plain-language definitions for the technical terms used above.
- BLE
- BLE stands for Bluetooth Low Energy, a Bluetooth mode designed for lower power use and modern phone compatibility. It matters because BLE support can make the module easier to use with Apple devices and battery-powered projects, though it may behave differently from classic serial Bluetooth.
- UART
- UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
