“Matrix Keyboards are awesome when it comes to controlling your PC (or even phone and tablet). One push of a button can start a macro, speeding up your workflow. And those keyboards are widely available. But what if you could build one yourself? And you want a touchscreen? Well… that is simple! And also cheap ;)
In this instructable I will build one using a Raspberry Pi Pico and a TFT with touchscreen.
Supplies:
a Raspberry Pi Pico
an ILI9488 TFT with Touchscree
Tools:
A soldering iron and solder.
Wire strippers (if you are not using the PCB).
Flush cutter.”
