The Raspberry Pi has an on-board audio jack, which is super handy for all kinds of sound effects and speech, just plug and go! However, for when you want better audio for music playback, a USB audio card can greatly improve the sound quality and volume. That's because the on-board audio is generated by a PWM output and is minimally filtered. Oct 28, 2016 · Leapfrog Bulletin Board is a kiosk web application powered by Raspberry Pi.
