ESP32-DA Hi-Fi USB Bluetooth Speaker (Open Source)

The DSTIKE-DA is a premium, open-source USB Bluetooth speaker that pushes the limits of the ESP32 platform. Featuring a custom 16MB Flash ESP32-WROOM-DA module and the MAX98357 I2S DAC, it combines massive storage for your code with superior signal stability and digital audio performance.

🚀 Why 16MB Flash?

While standard modules only offer 4MB, our custom 16MB version gives you 4x the space! This is perfect for:

• Large firmware builds (e.g., complex ESPHome configurations).

• Storing local MP3/WAV files for offline playback.

• Huge OTA (Over-the-Air) partitions for worry-free remote updates.

📡 Dual-Antenna "DA" Power

The "DA" module features two complementary PCB antennas. It intelligently handles signal reception to ensure a rock-solid Bluetooth link even in interference-heavy environments, providing a much longer and more stable range than standard single-antenna boards.
