The CyberFold Is a Slick, Sleek, Pocket-Sized Clamshell Built Around the Raspberry Pi Compute Module
Clever cyberdeck can host a Raspberry Pi Compute Module 4, Compute Module 5, or the cost-reduced Compute Module Zero on an interposer.
Pseudonymous maker "Eggfly" and colleague "MeiYao" have designed a compact clamshell cyberdeck looking more like a Nintendo Game Boy Advance SP with a keyboard than the surprisingly powerful laptop it is — hosting a Raspberry Pi Compute Module Zero, Compute Module 4, or Compute Module 5 inside.
"I call it 'CyberFold,'" Eggfly writes of the slick project. "A foldable cyberdeck that is compatible with [the Raspberry Pi] CM0 [or] CM4/CM5 [computers-on-modules]. With 1024×768 capacitive multi-touch main screen and minor touchpad screen showing battery percent and power cost [which] runs [on an Espressif] ESP32-S3 behind."
The machine looks for all the world like an oversized Nintendo Game Boy Advance SP handheld console, except where you would normally find the direction pad and fire buttons is a full QWERTY keyboard — a Solder Party KeebDeck open source silicone keyboard that Eggfly manufactured themselves from the original design files — and a compact touchpad, which doubles as a secondary display for battery status.
Inside the custom-designed housing is a motherboard that accepts the Raspberry Pi Compute Module 4 and Compute Module 5 families of computers-on-modules, the industrial- and embedded-focused versions of the popular Raspberry Pi 4 and Raspberry Pi 5 single-board computers respectively. It'll also accept, via an adapter board, the stamp-format Raspberry Pi Compute Module Zero, a cost-reduced design built exclusively for the Chinese market.
The board includes a range of ports, including full-size USB 3.0 and 2.0 ports for ease of expansion, plus an integrated holder for a pair of batteries linked to an internal charging circuit. There are built-in stereo speakers positioned either side of the screen, a scroll wheel based on a rotary encoder, two HDMI video outputs, a debugging port, and a microSD Card slot for storage when using the Raspberry Pi Compute Module Zero or the eMMC-lacking Raspberry Pi Compute Module 4 Lite or Compute Module 5 Lite models.
Full details are available in Eggfly's Reddit thread; design files had not been publicly released at the time of writing.
