With this Raspberry Pi 3 Model B / B+ / A+ DIY Proto HAT Shield RedDesign your own Pi HUT, attach after circuitry, and make your Pi A +, B +, or Pi 2 and Pi 3 shield. To kick off the HAT party, we have this proto inspired plug-in daughterboard.

 It has a grid of 0.1-inch prototyping soldering holes for attaching chips, resistors, LEDs, potentiometers, and more. The holes are connected underneath with traces to mimic the solderless standard mounting plates you are familiar with. 

There are also long power strips for + 3V, + 5V, and Ground connections to the Pi. Near the top, we break off almost every pin
