Pi Arduino Development Station

Having picked up a folding Plexiglas prototyping assembly for a few dollars at the amateur radio swap meet I decided to use it to build a portable Raspberry Pi Arduino prototyping station. I could use the Raspberry Pi 4 to do hardware development directly and with the Raspian Linux operating system I would be able to run the Arduino IDE.

The completed system consists of a Raspberry Pi 4, Arduino Uno, ten-inch HDMI display, and a USB receptacle outlet for power. There is also a proto board with assorted connections for easy hardware development and IO.

Here you can see where I added a prototyping board that includes a GPIO breakout connector for the Raspberry Pi. As with most of my prototyping setups I like to add an aluminum angle bracket to hold some BNC connectors for easy IO.

Here is a view of the banana jacks used for connecting external power supplies.

Here is where the completed project comes together where the Arduino is driving and reading an arrangement of gates and counters in a simple ‘Hello World” test.
