Microchip

The BM83 Bluetooth Audio Development Board (BM83 EVB) enables the user to evaluate and demonstrate thefunctionality of the BM83 audio module and IS2083BM System-on-Chip (SoC). This board is a complete, all-in-onesolution to develop multiple Bluetooth audio applications including portable speakers and headphones. The BM83EVB features an on-board PIC32 for Host MCU mode applications, an external codec to improve audio quality, adigital microphone to capture voice audio, indicator LEDs and buttons for ease of development.
