Arduino / Shields / Prototyping

This prototyping shield is the best out there (well, we think so, at least), and now is even better with Version R3 - updated for the most compatibility with just about all the Arduinos! It works with UNO, Mega, Leonardo, NG, Diecimila, Duemilanove, and compatible Arduinos. Yun's and Arduino Ethernets have a chunky Ethernet jack that gets in the way of stacking, you...

The next generation Proto-ScrewShield is a dual-purpose prototyping shield. Not only does it have a large 0.1" grid prototyping area but it also extends the Arduino pins to sturdy, secure, and dependable screw terminal blocks. You even get a few bonus terminals for extra GND and four 'free' terminals for whatever connections you wish! New! As of June 23, 2014 we now...

This is an extra large proto-shield, specifically designed for the Mega! It comes with PCB, two buttons and a full set of stacking headers. You can stack this shield easily since it comes with extra long female headers The kit includes: 1 x MEGAshield PCB. 2 x tactile switch. 1 x 3-pin male header. 1 x 2x3-pin stacking female header. 1 x 10-pin stacking female...

This shield kit pack will allow you to turn any Arduino into an AVR chip burner! It is specifically designed for people who want to program Atmega328P's to turn them into Arduino bootloader chips using an AVR-ISP sketch, but it can also be used to make a 'standalone' AVR ISP programmer - so that you can program blank chips without a computer! We use this set up in...

The patch shield is a cross between a patch panel/bay and a Wingshield. Its designed for times when you want to have remote sensors, or a control panel, or LEDs, or...practically anything where you want to avoid doing a lot of icky wiring! The shield comes with 4 breadboard-friendly satellite headers. To connect, use any off-the-shelf Ethernet cable. On the shield...

Works with the Uno! This prototyping shield is the best out there (well, we think so, at least). It works with UNO, NG, Diecimila and Duemilanove Arduinos. You can use it with a Leonardo but it will not break out the hardware SPI pins (they're only on the ISP connector underneath) or the IOREF/SDA/SCL pins. However, the SDA/SCL pins on the Leonardo are also on...

This is just the PCB for a proto shield. No other parts are included. This shield is designed for the Arduino Uno, NG and Decimila Arduinos. For parts list and instructions, please visit the website

Think you can do better? Design your own shield on the cheap with this DIY parts kit. You get a 3.2" x 2.5" (~ 8.1cm x 6.3cm) single-sided phenolic board with copper solder pads and mounting holes and a extra-special stacky header set. This one has one magical 8-pin header that has been bent so that you can plug it into the 'not-quite-0.1"-spacing" arduino headers...
