HandiPi

by brickbots · Hard · manifest draft — being verified

A Raspberry Pi 4 handheld with a 4.3-inch DSI touchscreen, PiSugar battery board, custom tactile keyboard, navigation switch and creator-published case files.

HandiPi packages a Raspberry Pi terminal into a compact printable shell. Its custom 36-button tactile keyboard, navigation control and creator-published PCB files make it more involved than a kit, while the DSI display and PiSugar board keep the main compute stack modular.

Notes

Draft: the creator explicitly says the BOM is not comprehensive. It leaves several passive ratings, the USB connector subtype, SD-card model, fastener dimensions/counts, wiring, heatsink and some assembly consumables unspecified. Custom PCBs must be fabricated from the creator files; BuildDeck does not host or redistribute them. The repository and its four published 3MF case files are MIT licensed. Confirm the remaining details against the PCB, schematic and case files before ordering.
