“This product is very good. I have used it to connect an RGB LED and buttons to my Raspberry Pi. I would highly recommend buying, I know I will be buying again at some point.”
“Neat breadboard. Can be used for building up circuits that connect to a Raspberry Pi's GPIO connectors or with a microcontroller plugged right in. Two or more breadboards can be clipped together to make a larger area, and the power rails can be unclipped from the sides to give a larger area for prototyping (which is needed for some large microcontroller breakouts).”
