The Papilio Breadboarding Wing is ideal for adding your own custom electronics to the Papilio. Plug into any 16-bit Papilio Wing Slot and have access to the Papilio's I/O pins through the convenient I/O header on the left. Ground is available on the right and 3.3V or 5V power is available on the top and bottom. Use jumper wires to connect any of the I/O or power pins of the Papilio to the 170 point breadboard in the middle. Wire up your favorite module or small electonics project and then plug and unplug it from your Papilio as it is needed! These boards are priced as low as we can get em so you can have several on hand for your projects.
