FUNCTIONS

Power supply

The KY-A2B Module operates on A2B bus power, simplifying wiring complexity and enhancing power management efficiency.

Analog Interface

It provides one bidirectional I/O channel that enables conversion and transmission between analog and digital signals.

Audio Transmission

It achieves bidirectional audio transmission through A2B engineered configuration, supporting upstream PDM/TDM formats (selectable from analog input or internal signals) while converting downstream master node signals to analog output for detection.

Non-Volatile Storage

It maintains waveform settings through power cycles, ensuring rapid system recovery after reboots.

Interface Upgrade

The external interface of the KY-A2B Module supports dip-switch-based upgrading, enabling hardware function expansion without software debugging.
