i.MX Audio Board is a configurable and functional audio processing platform. It supports multiple i.MX 8M series processors (including the i.MX 8M Plus, i.MX 8M Mini, and i.MX 8M Nano) and HDMI card boards. Integrating a variety of audio input and output interfaces into the system, the i.MX Audio Board supports HDMI input, HDMI eARC, S/PDIF I/O, 2-ch ADC line-in, 24-ch DAC line-out and more. Based on these features, rich audio application cases can be realized. The i.MX Audio Board may be used to evaluate NXP’s Immersiv3D™ Audio Framework Software. Together, the reference hardware and software dramatically reduce development time and cost for consumer audio devices with immersive sound.
