Beautiful new product Pi Hat for the Raspberry Pi 3! Amazing build quality using the latest chip technology to drive the UART serial port at RS232 baud rate. The traces are easy to follow on the PCB and it is to see which points and components are connected with each other. Has infrared receiver/emitter, a bright green LED to indicate power, and a whole bunch of pins receptacles both male and females for your hobby projects. Fits easily on top of my aluminum case as Pi Hat. Plug, reboot, and play

Love it. I use this to hook up vintage computing components to my Raspberry PI. This was the first plug-and-play RS-232 board I've encountered. I'll definitely get it again.

All looks fine

What we expected. perfect

As advertised, nothing to really report its just a simple expansion board..
