Good board, minor documentation issues

Hardware is solid and connects easily to Arduino IDE. However, the pinout diagram on the box was slightly faded. Otherwise, a great purchase for learning.

Best starter board for embedded systems

As a student, this was my first step into IoT. The community support is huge, and uploading sketches is incredibly fast compared to older boards.

Unbeatable price-to-performance ratio

You simply cannot beat this specs list at this price point. Wi-Fi and Bluetooth work out of the box with MicroPython. Highly recommended.

Reliable for home automation

Running several of these in my smart home setup. They stay connected well, though they can get warm under heavy load. Recommend adding a small heatsink for continuous use.
