The Raspberry Pi Zero is an amazing device packing a lot of capability into a $5 purchase. But the Zero does not come with the GPIO pins installed, leaving the installation up to the purchaser (that be you). I found soldering the pins more difficult that it should. I could never keep the pins steady while I soldered and balanced the Pi. Thus this "thing" was created. The Raspberry Pi Zero Soldering Holder will secure your Pi while you solder the missing GPIO pins.

It is designed to hold your Pi exactly 8.2 mm above the bottom plate. The pins rest securely in a small box assuring the correct alignment with the Pi.
