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-

the-Air (OTA).

This turn-key solution module pre-programmed with firmware that enables Bluetooth audio playback, for a plug-and-

play 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.
