https://www.amazon.com/gp/product/B09CTQ37DB (I got the 16x16 for $16). Another <$10 for the ESP32. A soldering iron ($40 for a pinecil), $verylittle for solder and hook up wire. In my case, a 3D printer ($500) plus filament ($20), and some design software ($500/year, because Fusion 360 expensive).
