Ellie ★★★★★

The I2C port makes connecting sensors so much cleaner than jumper-wire spaghetti. Booted up and connected to WiFi on the first try without any fuss.

Ellie Q. ★★★★★

Finally, a proper Type-C port on this board so I can stop hunting for micro-USB cables. The built-in I2C port saved me from soldering extra wires for my temp sensor. Works perfectly with my existing ESP8266 code.

Ryan H. ★★★★★

Got one of these for a home sensor project and the built-in I2C port on V4 saves so much wiring hassle. Pairing it with a BME280 was basically plug-and-play.
