Description
The BT201 Dual-Mode 5.0 Bluetooth Audio Amplifier Board is a highly integrated, versatile audio solution offering Bluetooth 5.0 connectivity, multiple input options (TF card, USB, AUX), and high-fidelity audio output. Its dual-mode capability (Classic Bluetooth and BLE) and AT command support make it a powerful choice for both standard DIY audio upgrades and complex industrial applications.
Description
The BT201 Dual-Mode 5.0 Bluetooth Audio Amplifier Board is a professional-grade audio module that seamlessly integrates wireless audio reception, digital decoding, and power amplification onto a single compact PCB. It utilizes the robust Bluetooth 5.0 protocol, supporting both Classic Bluetooth (BR/EDR) for high-quality audio streaming (compatible with A2DP, AVRCP, HFP, HSP) and Bluetooth Low Energy (BLE) for advanced data communication via SPP serial port and AT command control.
Unlike basic receiver boards, the BT201 offers exceptional flexibility with multiple audio inputs: Bluetooth wireless, TF card, USB disk playback, and a 3.5mm AUX line-in jack. The board features an onboard 2x5W stereo amplifier, capable of driving passive speakers directly, eliminating the need for an external amplifier in most standard applications.
The true strength of the BT201 lies in its customizability and control options. With support for AT commands via the serial port (UART interface), users can manipulate the module’s behavior, switch audio sources, control playback, and even modify broadcast names, making it an ideal solution for business purchasing and custom product integration. The integrated 3W/5W mono Class D amplifier output is suitable for various speaker impedances (typically 2Ω to 8Ω).
