Perfect for IoT starters
Great board for the price. Flashed easily with Arduino IDE and connected to my home Wi-Fi without issues.

Good but needs driver
Board works well but had to install CH340 drivers first before my computer recognized it. Once set up, it works great.

Solid performance
Running MQTT without issues. GPIOs are accessible and the breadboard friendly design is a plus.
