Overview: BM83
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 is pre-programmed with firmware that enables Bluetooth audio playback for a plug-andplay solution, and an audio transceiver solution for A2DP source/sink. 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 applications.
Note: Contact your local sales representative for more information about the Software Development Kit (SDK).
