Great for IoT projects
Works perfectly with Arduino IDE. The CH340C driver was easy to install on Windows 10. Very stable Wi-Fi connection.

Driver issues initially
Had to install CH340 drivers manually before the computer recognized the board. Once set up, it works fine.

Good value board
Pinout diagram could be clearer on the silkscreen. Otherwise, performance is solid for the price point.
