🔉 The S3-1200 Audio Brain PCB Comes to Life

Huge thanks to PCBWay for manufacturing the PCBs used in this build and supporting the project! 👉 https://pcbway.com/g/GWd2X2 In this video, we assemble the Audio Brain PCB for the S3-1200 sampler project. This board contains the core audio hardware responsible for sampling, playback, and storage. The Audio Brain integrates several key components including the ESP32-S3, PCM1808 audio ADC, PCM1681 multi-channel DAC, a 3.3V voltage regulator, and an SD card module used for storing audio files. Together, these components form the heart of the sampler’s digital audio system. After populating the PCB with both surface-mount and through-hole components, we walk through the assembly process, soldering techniques, and module installation. Once the board is complete, we connect it to the power supply and control ESP32 to perform the first hardware test. To keep the initial test simple, the outputs are temporarily connected through 10µF coupling capacitors without the final filtering or amplification stages. This allows us to verify that the core digital audio system is working before committing to the final analog output design. We also demonstrate how easy it is to order PCBs directly from KiCad using the PCBWay plugin, which automatically uploads Gerber files and BOM data to streamline the manufacturing process. https://www.pcbway.com/blog/News/PCBW...
