    BT Audio 2 Click is Bluetooth audio stream add on board based on BM62 module from Microchip. It's a Stereo Audio module which is fully qualified Bluetooth v5.0 dual-mode (BDR/EDR/BLE) to be added in any wireless audio and voice application. With features like high resolution up to 24-bit, 96 kHz audio data format, Bluetooth Low Energy data rate up to 1Mbits/s, connection of two hosts with HFP/A2DP profiles simultaneously, seamless serial data over UART interface and many more it's perfect solution for applications like portable speakers and headsets.

    BT Audio 2 Click board™ is supported by a mikroSDK compliant library, which includes functions that simplify software development.

    BT Audio 2 Click includes advanced audio features, such as multi-band dynamic range control, parametric multi-band equalizer, audio widening and virtual bass are inbuilt. The audio effect algorithms improve the user’s audio listening experience in terms of better audio quality after audio signal processing.

    The input and output audios have different stages and each stage can be programmed to vary the gain response characteristics. A Digital Signal Processor (DSP) is used to perform speech and audio processing. The advanced speech features, such as acoustic echo cancellation and noise reduction are inbuilt. To reduce nonlinear distortion and to help echo cancellation, an outgoing signal level to the speaker is monitored and adjusted to avoid saturation of speaker output or microphone input.

    BT Audio 2 Click supports one analog (line-in) signal from the external audio source. The analog (line-in) signal can be processed by the DSP to generate different sound effects (multi-band dynamic range compression and audio widening), which can be configured by using the DSP tool. Also, module has an AFH function to avoid RF interference. It has an algorithm to check the nearby interference and to choose clear channel for transceiver Bluetooth signal.

    The on-chip Power Management Unit (PMU) has two main features: lithium-ion and lithium-polymer battery charger, and voltage regulator. A power switch is used to switch over the power source between the battery and an adapter. Also, the PMU provides current to drive two LEDs. The LED and button settings can be configured.

    This Click board™ uses the UART communication interface and is designed to be operated only with a 3.3V logic level. A proper logic voltage level conversion should be performed before the Click board™ is used with MCUs with different logic levels.
