As an introduction to embedded electronics and programming in a straightforward environment, there isn’t much out there that can hold a torch to the Arduino Uno. Cheap (especially if you count the clones), easy to find, and quick to deploy, with countless support libraries, it’s a go-to for many a hack. This scribe simply can’t remember how many he’s bought, hacked, and deployed over the years. But can it be improved? [John Loeffler] thinks so, and his 2023 Hackaday Prize entry, the Uno Plus+ could be the one.

If this is too much bling for you, there is a version with LEDs adjacent to non-illuminated headers.

If this is too much bling for you, there is a version with LEDs adjacent to non-illuminated headers.

After clearing the top deck of extraneous components (by shoving them on the bottom) there was much more space to expand the header labeling, so there can be no accidental misplacement of those DuPont wires this thing will inevitably sprout randomly.

The board also has an additional Stemma/Qwiic connector and a Neopixel LED for indication duties. Also sitting on the PCB bottom are a ton of opamps, to drive the header indicators. Yes, this board has a full set of colour-coded LED bling indicators, showing the logical state of each and every pin on all headers, giving an easy way to check the desired activity is occurring. Plus it looks cool. Illuminated headers? YES!

Think the Uno too light on resources to perform any meaningful modern workloads? Think again!
