Excellent value for memory size
16MB Flash and 8MB PSRAM at this price point is hard to beat. Compiles and uploads quickly via USB-C.

Great board, minor pin labeling issue
Performance is excellent and Wi-Fi range is good. Just wish the pinout diagram on the back was slightly clearer. Otherwise recommended.

Perfect for AIoT projects
The N16R8 memory configuration is exactly what I needed for my voice recognition project. Works flawlessly with ESP-IDF.
