A 10 key keypad in matrix layout with feather pin configuration. Additionally there is an RGB led, a side power switch and 3 solder pads for battery (not included) / haptic feedback motor (not included).
Why did you make it?
I needed a small presentation remote and I liked to play with a matrix key configuration. It couples perfectly with the Adafruit Huzzah32 board and it's meant to provide a very small package.
Sample code is shown that allows to scan they keyboard and react to press/long-press events/release events. I added an RGB LED since the Huzzah32 doesn't come with one and I left some pads in the back to connect to a small motor for haptic feedback.
What makes it special?
The small form factor, while at the same time providing buttons that are large enough to be felt/pressed with medium sized fingers.
