Pi Jumper

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.

Please note: Pi Jumper is supplied as a kit for the buyer to assemble by soldering the components to the printed circuit board.

Your Raspberry Pi is running, and you want to start playing with all the great I/O abilities of your Pi.

But where to start?

There are 26 pins on the main expansion connector – and they are not labelled!

You can start with Pi Jumper – it has clearly labelled connectors, and a lot more…

Pi Jumper is much more than a simple breakout for the Raspberry Pi expansion connector!

Did you know that the Raspberry Pi is only designed to supply 50mA from its 3.3V output? Granted, you can often draw 100mA, but why take a chance?

Pi Jumper 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 – the Pi Jumper’s voltage regulator can supply 600mA (assuming the 5V from the Raspberry Pi has enough capacity in your system).

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

There are a lot of nice I2C add-on boards out there… and some require a 5V I2C interface.

Pi Jumper provides both 3.3V and 5V I2C interfaces for the Raspberry Pi’s I2C bus – allowing you to use both 5V and 3.3V I2C modules and integrated circuits!

I could go on about the easy to read silk screened Raspberry Pi, dual I2C, and 20 pin breadboard connectors, but I’ll let the photographs below tell the story.

Raspberry Pi, SchoolBoard ][ and Breadboards NOT included. Pi Jumper is supplied as a kit you must assemble yourself.

Fine print: Of course, like with any electronics add-on, you have to make sure you get the polarities right, otherwise you could damage your Raspberry Pi – and we are not responsible for your wiring, assembly or other mistakes. If you are careful, you could even power your Raspberry Pi with a regulated power supply at the screw terminals!
