Perfect for IoT projects
This board works flawlessly with the Arduino IDE. WiFi connectivity is stable and the dual-side pin layout makes breadboarding much easier.

Good value but small
Great little board for the price. Just be careful with the voltage levels as it is 3.3V logic. Otherwise, it performs well.

Fits breadboard perfectly
The form factor is exactly what I needed. It sits snugly on the breadboard without blocking adjacent rows.
