Good but Warm
Functions well but gets a bit warm during sustained Wi-Fi transmission. Might need a heatsink for heavy load applications.

Easy to Start
Worked out of the box with Arduino IDE. Drivers installed automatically on Windows 11. Highly recommend for beginners.

Solid Performance
Good connectivity and speed. Wish the pinout diagram was clearer in the box, but overall a reliable board.

Great Value
16MB flash and 8MB PSRAM at this price point is unbeatable. The N16R8 module performs exactly as specified.
