Waveshare ESP32-S3 Mini Dev Board w/ 8MB Flash & 8MB PSRAM

The board is fully compatible with Espressif's official ESP-IDF (IoT Development Framework) for advanced feature control, the Arduino Core for ESP32 via the Arduino IDE for beginner-friendly coding, and MicroPython for Python-based rapid scripting and prototyping. You can program it via the onboard USB Type-C connector.

Power is supplied via the onboard USB Type-C port at 5V DC. An internal regulator steps this down to the 3.3V logic level required by the ESP32-S3 chip and its GPIO pins. Ensure your USB power source provides a stable 5V output with sufficient current for your connected peripherals.

Yes, the board features a castellated (half-hole) edge design specifically for surface-mount assembly. You can solder it directly onto a carrier PCB, integrating it as a compact system-on-module (SoM) for your final product design, which saves space compared to using headers.

The 8MB Pseudo Static RAM (PSRAM) provides a large, fast external memory pool crucial for data-intensive tasks. It allows for buffering high-resolution images, storing audio samples, handling complex graphics, and running larger machine learning models that would not fit in the chip's internal SRAM, enabling advanced edge AI applications.
