About this item

The PT8211 Unassembled Audio Kit is a simple and cost-effective digital-to-analog converter (DAC) designed for use with Teensy 3.x development boards. It utilizes the PT8211 stereo DAC chip, offering 16-bit stereo audio output through the I²S (Inter-IC Sound) interface. This kit is ideal for hobbyists, students, and developers seeking basic audio output capabilities for projects involving synthesized sound, audio playback, or signal generation. Unlike the more complex SGTL5000-based audio boards, the PT8211 kit focuses solely on DAC output, making it an excellent choice for minimalist audio needs or compact embedded applications. It’s fully supported by the Teensy Audio Library, which allows users to build advanced audio processing chains via a user-friendly graphical interface in the Arduino IDE. The kit comes unassembled, giving users the opportunity to practice soldering and customize the layout if needed. Once assembled, it connects directly to the Teensy 3.x via I²S pins and provides clean analog audio output. While it doesn’t support features like audio input or headphone amplification, its low power consumption, ease of use, and low cost make it a practical solution for basic audio generation projects.
