Okay, okay, okay. Let me introduce you to Nexus-4, a custom 4-key macropad. It features an inverted-T arrow key layout, a 128x32 OLED display, and a 3D-printed sandwich-mount case. So I run the the software of this on a Seeed Studio XIAO RP2040 that runs my custom QMK firmware. I

So I run the the software of this on a Seeed Studio XIAO RP2040 that runs my custom QMK firmware. I've even made some simple ASCII art animations(currently very simple tho)!

The cadded box I made for the macropad is a sandwich-mount structure, and I made it on Fusion 360. The PCB rests inside this enclosure, and it is topped by the Top Plate, which is secured using screws at the four corners. I've also made a side…
