The trackpad is powered by a Raspberry Pi RP2040, while finger tracking is handled by a Microchip ATMXT1066TD processor which can all be found on a single mainboard that’s easy to swap into another case. Although Ploopy says the included 3D-printed case “has a fantastic surface finish” and is “great to use all day,” you can download the case’s open-source design files to print it using a different material or change its design entirely.
