About this item

The TEENSY4-AUDIO Audio Board (Rev D) is a high-quality, feature-rich audio interface designed to integrate seamlessly with the Teensy 4.0 and 4.1 development boards. Built around the SGTL5000 stereo codec, this board enables high-fidelity audio input and output, supporting a wide range of digital signal processing (DSP) applications including real-time audio effects, music synthesis, voice processing, and more. The board includes a 16-bit stereo DAC and ADC, supporting sample rates up to 44.1kHz, with low-latency audio performance. It connects easily to the Teensy via I²S (Inter-IC Sound) and I²C protocols, and works out-of-the-box with the Teensy Audio Library, which provides a flexible and powerful visual tool for designing audio signal chains. Rev D adds compatibility improvements specifically for the Teensy 4.x series, including support for digital audio through the MEMS microphone input, and improved pinout and layout. Onboard features include line-level input/output, headphone output, and volume control via software. It also provides solder pads for optional SPDIF, MIDI, and SD card expansions, making it ideal for custom audio hardware development. Perfect for makers, musicians, and audio engineers, the TEENSY4-AUDIO board delivers professional-grade audio in a compact form factor.
