What is it?

Designed for educational users and hobbyists, Pi Jumper is the best way to break out the Raspberry Pi’s I/O header for prototyping with solderless breadboards.

PiJumper works with Raspberry Pi models A/A+/B/B+ and Raspberry Pi 2.

Please note: Pi Jumper is supplied as a kit for the buyer to assemble by soldering the components to the printed circuit board. Raspberry Pi, wires and breadboard not included

Why did you make it?

I designed Pi Jumper to be able to experiment with Raspberry Pi I/O more easily, and to provide both 3v3 and 5V I2C connectors.

Pi Jumper also adds an LT1117-3.3 (or equivalent) voltage regulator powered from the Raspberry Pi expansion connectors 5V output, so you don’t have to worry about the Pi’s 3.3V current limits on earlier Pi's.

Pi Jumper provides a three screw terminal so that you can run 5V / 3.3V / GND to your breadboards power strips.

What makes it special?

The dual 3v3 and 5V I2C connectors, the clearly labelled I/O connection points, and the 3v3 regulator.

Pi Jumper Features

• stacking header for the Raspberry Pi
• On-board voltage regulation providing 3.3V from the 5V on the Pi header
• LED power indicator
• four pin 3.3V I2C expansion header
• four pin 5V I2C expansion header with voltage translation
• 20 pin male header, and 20 pin round female header so you can choose between
• a) male header on top for female-to-male jumper wires
• b) female header on top for using any cut wire or jumper wire
• c) male header on bottom for plugging directly into a breadboard
• three screw terminals for 5V / 3v3 / GND
• Mikronauts EZasPi prototyping board can stack above and/or below Pi Jumper
• Can stack on Mikronauts RoboPi and PiDroidAlpha robot controllers
