Perfect for IoT Prototyping
This board works straight out of the box. The OLED display is crisp enough for status messages and the Wi-Fi connection is stable. Highly recommend for beginners.

Decent but display is dim
The functionality is fine, but the OLED brightness is hard to adjust and seems dim in bright rooms. Good for indoor low-light projects only.

Excellent Support
Had issues with drivers initially but the support team helped me resolve it quickly. The board itself is very reliable for home automation tasks.

Compact Powerhouse
Love the built-in screen. It saves so much space compared to wiring an external display. Bluetooth pairing was quick and easy.
