USB-C is a game changer
Finally no more micro-USB cables. Flashing code is fast and reliable. Highly recommend for modern projects.

Low power consumption
Using this for a battery project and the sleep modes work perfectly. Great efficiency for the price point.

Good value for money
Easy to set up with Arduino IDE. Wish it came with headers pre-soldered, but otherwise excellent board.

Perfect for IoT prototypes
The size is incredibly small yet packs all the features I need. Wi-Fi connection is stable and setup was straightforward.
