v19 (new c0)(query does anyone know of a mechanical numpad that has a screen and the ability to run custom firmwareideally with more buttons than a normal numpad
it doesn't have to be pre-assembled, but I do need at least the display and the PCB
I know mechanical numpads that can work as a calculator exist, but I want an RPN one and it seems like I'd need to at least write the firmware
