Great value for money

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

Good board, minor documentation issues

Hardware is solid. WiFi range is decent. Wish the pinout diagram was clearer in the box.

Solid performance

Using it for sensor nodes. Bluetooth pairing is stable. Only wish it had more ADC pins.
