Description: This is the SparkFun Pi Wedge, a small board that connects to the 40-pin GPIO connector on the Raspberry Pi and breaks the pins out to breadboard-friendly arrangement and spacing, and even adds a couple of decoupling capacitors on the power supply lines. The “Wedge” also makes the initial bring-up process easier - you can plug an FTDI Basic module into the built-in serial port. Each version of this Pi Wedge comes preassembled and can be inserted into the RPi’s GPIO port that allows you to prototype - no soldering required!

The Pi Wedge is compatible with the Raspberry Pi A+, B+, or RPi2 models and it adapts the GPIO header on the RPi to a standard solderless breadboard, such as our medium, large, and extra large breadboards. While it will technically with with a mini breadboard, it won’t leave much room for external circuitry. If you love the Raspberry Pi and have been looking to start prototyping with it look no further than the SparkFun Pi Wedge!

Customer Comments

  • Does it work the same with RPI 3 ?

  • Hey everybody, I think I mapped out the pins on the wedge, for anyone using the wiringPi C library. NOOBS 2.1.0, RPi 3. If you have a different pinout or you can verify this, please comment and correct or verify! Thanks! Couldn’t find this anywhere.

    EDIT: Thanks Toni_K, looks like that works and just what I needed.

Functions well

Fits through my standard Pi Tin. No problems as of yet.

Really Good Buy (Most of the time)

The Pi wedge is one of the better additions I’ve seen for the Pi. Makes serial connections super easy. I have about a dozen or so of the Pi Wedges. Unfortunately, a few of them have come in with the 40 pin header soldered backwards. It took quite some effort to pull it off and solder it facing the right way. I would say if it comes reversed just return it.

Pi Wedge

I really like the Pi Wedge. Makes it much easier to get to all 40 pins, and the pin grouping is more logical than the Pi itself. Arrived fast and in perfect condition.

Makes prototyping faster

Raspberry Pi has an annoying male connector that is very inconvenient for prototyping with breadboard. The Wedge solves this issue for good.

Helpful little widget

Dealing with the pins on the Raspberry Pi was annoying and this is a great solution.

Excellent Quality

Excellent Quality!!! The option for connect FTDI is great
