I am building controllers using a Raspberry Pi 3 and used jumpers to connect to the Pi until I found them. The circuit boards are very well designed, every hole is soldered and ready for soldering. All external connections to relays, opp, ph, tds and more are jumpered onto this small board. This makes it easy to service the Pi, including swapping it out. It was so easy that I rebuilt another controller with this board. I will never create a Pi project again without this board. The connectors are not soldered but as said they are very well constructed and so easy to solder it is very easy to do.
