Hi-Fi Sound Card HAT for Raspberry Pi (with speakers)

This is a Hi-Fi Sound Card HAT designed for the Raspberry Pi, a great option for anyone wanting to record or play high-quality audio from their Raspberry Pi. The HAT comes with a pair of 5W speakers and features low power consumption, Hi-Fi playing/recording, stereo encoding/decoding and can directly drive speakers to play music. There's also a button on the board tied to GPIO 17 which you can use in your project. The onboard high-quality MEMS silicon microphone supports left/right channel recording, whilst the 3.5mm jack allows headphone playback if preferred for your project. Features
