The Ploopy trackpad, 3D-printed and open-source, offers extensive customization.
Translate the following summary: Do it your way.
Ploopy has expanded its range of customizable peripherals with the addition of a new seven-inch trackpad that supports multi-touch gestures and features palm rejection. Like Ploopy's mouse and trackballs, this trackpad operates under the open-source QMK firmware, allowing for greater customization in its functionality.
The device is powered by a Raspberry Pi RP2040, while finger tracking is managed by a Microchip ATMXT1066TD processor, all integrated into a single mainboard that is easy to transfer to another chassis. Although the company claims that the included 3D-printed case "has a fantastic surface finish" and is "great for all-day use," it is also possible to download the open-source design files for the case to print it with other materials or modify its design.
The Ploopy trackpad is available in gray and black tones, although a custom case can also be 3D printed in any color. This trackpad is slightly larger than Apple’s Magic Trackpad, but its tracking area is a bit smaller, reaching over six inches. Nonetheless, it provides enough space to perform gestures with up to five fingers, although currently, its compatibility is limited to Windows and Linux.
The device needs to be connected to a PC via USB at all times, as it does not include wireless capabilities. While this could be a potential modification, it might be complicated due to the limited support of QMK for Bluetooth hardware.
The Ploopy trackpad is already available in two different options. You can pre-order a fully assembled, ready-to-use model in black or gray for an approximate price of $94 (equivalent to $129.99 in Canada), or purchase a DIY kit that requires tools such as a screwdriver, pliers, and a wrench for assembly, for about $73 ($99.99 in Canada). The estimated delivery time for both options is "up to 20 weeks from the order date."
