BM83 Bluetooth
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.
