Microchip Technology BM63 BLUETOOTH® Audio Evaluation Board
Microchip Technology BM63 Evaluation Board provides a demonstration and development platform for the BM63 BLUETOOTH® 4.2 Dual-Mode Stereo Audio Module. The BM63 Module enables designers to easily add BLUETOOTH® wireless audio and voice functionality to applications.
The BM63 Evaluation Board's integrated design features a programming interface for plug-and-play capability and rapid prototyping. Additional features include a built-in 3W Class-D stereo audio amplifier, built-in near field communication (NFC), stereo audio output, and data and connection status LEDs.
Designers can configure the board to be controlled by a host controller via a simple MCU connector or operate stand-alone mode.
Features
- Based on the fully-certified BLUETOOTH® 4.2 BM63 stereo audio module
- On-board MCU (PIC18F85J10) and DSP audio amplifier for easy operation and feature demonstration
- Powered by a PC host using the micro-USB cable or by connecting a Li-Ion battery
- Built-in 3W Class-D stereo audio amplifier
- Built-in Near Field Communication (NFC)
