EV6550DHAT Raspberry Pi HAT for CMX655D Low-Power Voice Codec

CML Microcircuits' EV6550DHAT Raspberry Pi HAT designed for hardware and software solutions

Image of CML Microcircuits' EV6550DHAT Raspberry Pi HAT for CMX655D Low Power Voice CodecThe popular Raspberry Pi has proven to be a phenomenal success: a hardware and software solution that has encouraged individuals, engineers, and design teams to develop countless unique projects.

CML Microcircuits' EV6550DHAT brings together the Raspberry Pi and the CMX655D ultra-low-power voice codec in a convenient way, enabling easy demonstration of the CMX655D and providing improved low power audio capabilities to the Raspberry Pi. This is achieved using common hardware and open-source software, simplifying its use and simplifying software and hardware development.

The CML CMX655D ultra-low-power voice codec integrates two matched channels supporting a large variety of digital MEMS (micro-electromechanical systems) microphones and signal processing capability along with a 1 watt high-efficiency Class D speaker amplifier.

As an inherently low power codec, the EV6550DHAT is ideal for use in low-power projects and developments typically based on the Raspberry Pi.
