Audio Development Board User's Guide
Introduction
The BM83 Bluetooth Audio Development Board (BM83 EVB) enables the user to evaluate and demonstrate the
functionality of the BM83 audio module and IS2083BM System-on-Chip (SoC). This board is a complete, all-in-one
solution to develop multiple Bluetooth audio applications including portable speakers and headphones. The BM83
EVB features an on-board PIC32 for Host MCU mode applications, an external codec to improve audio quality, a
digital microphone to capture voice audio, indicator LEDs and buttons for ease of development.
In addition to the BM83 EVB, the IS2083 SDK and IS208x_Config_GUI_Tool (Config Tool) are provided to customize
the audio processing settings.
