RasPiO Duino puts the capabilities of Arduino right on a Raspberry Pi

Arduino + Raspberry Pi = RasPiO Duino 

For those who’ve ever developed an electronics project and wished to combine a multi-tasking application with real-time and analog features, there’s now a simple add-on solution.


While the Pi is 40 times faster when it comes to clock speed, runs an actual operating system in Linux and offers a wide-range of connectivity options, the Arduino has become a Maker-favorite for precise real-time applications, analog inputs/outputs and instant boot. Not to mention, the simplicity of the Atmel based Arduino makes it a much more suitable option for pure hardware projects.

That was until the RasPiO Duino came along. Created by Alex Eames of RasPi.TV, the board aspires to make the collaboration between Raspberry Pi and Arduino easier and more efficient. The device, which recently made its Kickstarter debut, is engineered as an add-on for the Pi and is based on an ATmega328.

“I want to get you into the wonderful world of Arduino programming, using your Raspberry Pi as the programmer. There’s so much you can do with the ATmega328 microcontroller — it complements the Pi perfectly and for many applications it doesn’t even need to be connected to the Pi, once it’s programmed,” Eames writes.


RasPiO Duino currently works with a variety of Pi models, including A, A+, B, B+ and Pi2, while providing Makers with the full capabilities of an Uno, most notably its 14 digital I/O pins, 6 analog inputs, 6 hardware PWM outputs and real-time processing. Furthermore, its creator shares that the AVR powered board can be programmed from a Pi using the Arduino IDE.

The RasPiO Duino can be used one of two ways, either in co-processor mode or standalone. Once programmed, RasPiO Duino can be removed from the Pi and run on its own. Meanwhile, Makers can use it to control robots (up to 12 servos), read sensors, as well as switch things on/off. For those looking to leave it on and have the Pi interact with it, this can also be done via the serial interface. Simply connect two jumpers Tx & Rx.


“But I don’t want to just throw hardware at you and let you drown. I want to bring you a set of supporting materials to ensure you have a positive experience — even if you’ve never done these things before,” Earnes adds. “So there will be a set of structured experiments that will lead you through how to use it in a way that you will enjoy.”

Interested in experiencing the best of both DIY electronics worlds? Head over to the project’s official Kickstarter page, where Earnes is currently seeking £3,456. Pending all goes to plan, shipping to early backers is expected to begin in May 2015, with all deliveries slated for June.
