BM83 Bluetooth® Stereo Audio Module Data Sheet
Introduction
The BM83, based on Microchip’s dual-mode IS2083 system-on-chip (SoC) device, is an RF-certified, fully integrated
module with high-performing voice and audio post-processing capability for Bluetooth audio applications. Tuning for
Noise Reduction, Acoustic Echo Cancellation (AEC), and EQ filtering can be customized with an easy-to-use GUI
Configuration Tool. This flexible platform provides multiple digital and analog audio interfaces including stereo
microphones, I2S, Line-In and a stereo audio DAC. It supports easy firmware upgrades via UART, USB and Over-theAir (OTA).
This turn-key solution module pre-programmed with firmware that enables Bluetooth audio playback, for a plug-andplay solution. Control settings for LED drivers and other peripherals can be set via the Configuration Tool. Advanced
developers can use the Software Development Kit (SDK) to implement their embedded applications.
Note:  Contact your local sales representative for more information about the Software Development Kit (SDK).
