The Pi Spade is an adapter board designed to make it easier to attach a Raspberry Pi Zero to a breadboard. Generically, it can be used to adapt any 2x20 header to a breadboard by spacing each 20-pin row around the breadboard center.

Here is the basic layout.

Three separate headers are required to assemble the Pi Spade. Links are for convenience only. There are many variants to choose from.

• 1x20 male pin header
  • This is the set of pins that mirror one side of the Pi header across the center of the breadboard.
• 1x20 socket header
  • This is the side of the Pi header that is mirrored by the above part.
• 1x20 socket, stackable header
  • This extends one side of the Pi header directly to the breadboard.

The most convenient arrangement for a Raspberry Pi Zero is to use right a right angle header so that the Pi can plug directly to the Pi Spade vertically.
