Great value for money
Switched from ESP8266 to this. The RISC-V architecture is fast and efficient. USB-C is convenient.

Perfect for E-Paper Projects
Works flawlessly with my 2.9 inch e-ink display. Low power consumption is a huge plus.

Good board, minor documentation issues
Hardware is solid. WiFi range is decent. Wish the pinout diagram was clearer in the box.

Easy to program
Works straight out of the box with Arduino IDE. No driver installation headaches on Windows 11.
