Great for prototyping
Works perfectly with Arduino IDE. The onboard CH340G makes programming much easier than using an FTDI adapter.

Solid build
Pin headers were not soldered which is expected, but quality of the PCB is excellent.

Good budget option
Had to install drivers manually on Windows 10, but once set up it works flawlessly. Good value for the price.

Compact size
Fits easily into small enclosures. I use it for sensor nodes and it handles the workload well.
