The SCADuino Primo – a proof-of-concept SCADBoard
By: J. Pagliaccio and B. Reidy March 2014
3D Printed Breadboard Arduino
SCADuino is a 3D printable version of the Breadboard Arduino at Arduino.cc. Using OpenSCAD and the SCADBoard library it is easy to create a 3D printable breadboard like the Breadboard Arduino.
SCADuino created using SCADBoard
The design for the Breadboard Arduino can be found at the Arduino website here: http://arduino.cc/en/Main/Standalone The Arduino site has a step-by-step instruction for assembling the boards plus a bill of materials – the necessary components. All of the components are easy to find on https://www.sparkfun.com/ and https://www.adafruit.com/. We built the Breadboard Arduino first and used it as a reference to build our SCADuino. We also recommend using an Arduino Uno R3 like this https://www.adafruit.com/products/50 for programming the SCADuino. We program and then pop out the Atmega328 and put it in the SCADuino.
The SCADuino Code
We developed two versions of the SCADuino; one with normal size thru holes and one with oversized thru-holes that will fit 2 wires in each hole. Both versions are included in the SCAD file. The code is straight forward with comments in the code. The pictures represent the 2-wire version. Please note the SCADBoard library is at http://scadboard.wordpress.com/.
