The ESP32-A1S is the most underrated ESP32 board out there
Some ESP32 boards become community favourites because they're small, cheap, or easy to flash. The ESP32-A1S (known also as the "AI Thinker") became popular for a different reason: it promised an audio-capable board on a budget years before the modern wave of ESP32-based smart speakers, dev kits, and AI modules. But despite being one of the few ESP32 boards designed from the ground up for serious audio work, featuring an onboard ES8388/AC101 DAC/ADC, dedicated amplifier circuitry, headphone jack detection, and a layout meant for real playback rather than just experimentation, it never quite earned the mainstream recognition it deserves.
