Introduction

BM83 is a fully integrated, RF-certified module based on the Microchip dual-mode IS2083 system-on-chip device, designed for Bluetooth audio applications with high-performance voice and audio post-processing capabilities. Noise reduction, acoustic echo cancellation, and equalizer filtering can be customized via an easy-to-use GUI configuration tool. This flexible platform offers multiple digital and analog audio interfaces, including stereo microphone, I2S, line input, and stereo audio DAC. Firmware upgrades are supported via UART, USB, and OTA. This plug-and-play solution comes pre-loaded with firmware, enabling Bluetooth audio playback and A2DP source/sink audio transceiver functionality. LED driver and other peripheral control parameters can be configured through the configuration tool. Advanced developers can use the SDK to implement their applications. The BM83 module supports the following Bluetooth profiles and codecs: Hands-Free Profile 1.7.2, Headset Profile 1.2, Advanced Audio Distribution Profile 1.3, Serial Port Profile 1.2, Audio/Video Remote Control Profile 1.6, and Phone Book Access Profile 1.2; codecs include AAC and SBC.
