Proto Hat Documentation
This proto HAT (Hardware Attached on Top) is compatible with Raspbery Pi having 40 pins. The headers are soldered on and all the 40 pins are broken out on two rows below. The layout diagram will make it clear. So after soldering all the headers you have access to all the 40 pins.
Proto HAT has miter on corners and the mount hole match with Raspberry Pi.
I’m relatively new on selling wares on Tindie. I made this proto hat for my use and ordered some extras for a trial run. Good news is I managed to sell all on them without any sort marketing. Also I got some invauable feedback from users. As soon as I ran out of stock I ordered new one with the improvements suggested by one the users. Due to the chinese new year, it took some time to get the new boards, got them yesterday.
