IoTBits AudioBit – SGTL5000 Audio Codec Module

Add crystal clear, smartphone-like audio playback and recording capability to your embedded applications with our AudioBit audio codec module.

Built around the NXP SGTL5000 ultra-low power audio codec chip, this little module can add a ton of audio features to your design, such as voice recognition, high quality recording and playback capability, audio post processing and digital audio playback.
The AudioBit offers bass enhancement, surround sound, multi-band equalizer and pop-less, ramped audio adjustment operations.

AudioBit features extremely low power consumption and integrates 30mW stereo headphone drivers for clean, loud audio output. On-board low-noise, high PSRR LDO regulators provide clean audio power rails. A high-quality 1.6mm thick PCB ensures durability, while a well-laid out board provides the best audio performance you can get on your breadboard. We even added a ferrite bead to filter digital noise from the audio section, nothing is an overkill in audio!
