Open Laptop


Open Laptop – Open Hardware and Software Modular Laptop Project

Open Lunchbox could be the first open source modular laptop. The problem is that the silicon vendors have stopped releasing open source to the firmware.

AMD made a decision back in 2014 to supply AGESA as binary-only for future AGESA releases.

We could offer all the design files, mainboards and laptop components as kits, parts or as complete assembled and tested modules.

  • All the design and fabrication files will be open and free.
  • All the Linux drivers are open source.
  • The coreboot source will be hosted at the GIT repo.
  • Is an actual laptop
  • Modular Design
  • Standard locations for interconnects between cpu, battery, display and battery modules
  • Low cost without sacrificing quality and reliability.
  • Designed for professional laptop users and mobile computing enthusiasts.
  • Flexible design for laptops with different feature sets or as an open developer platform.
  • The design files may be used as a reference or standard to build modular laptops the same way desktop PC’s are made.




  • 2 and 4-core AMD64 APU’s, AMD ARM64, other ARM SOC’s are possible
  • Standard size CPU modules
  • 3D printed rapid SLA enclosures using engineering resins
  • CNC machined aluminum enclosures and cast alloy chassis
  • Thinkpad T60 type keyboards
  • Multiple display sizes 12″, 15″, 17″ etc
  • High capacity internal lithium-ion batteries and external battery packs
  • ECC support
  • Multiple display support
  • Supports 4-lane DisplayPort 1.2, DVI, HDMI 1.4a
  • Integrated VGA
  • Integrated eDP or 18bpp single channel LVDS
  • Multiple links of PCIe Gen 2 and 3 including mini-PCIe
  • 8 USB 2.0 + 2 USB 3.0
  • 2 SATA 2.x/3.x (up to 6Gb/s)
  • SD Card Reader v3.0 or SDIO controller
  • EC for battery charging and power management
  • M.2
  • SPI
  • LPC
  • SMBus
  • Gb Ethernet
  • WiFi
  • Unused GPIO routed to headers
  • Coreboot

Why an AMD APU?
AMD is the cpu of choice for its support of coreboot and open documentation. There are a few Intel laptop chipsets and cpus supported by coreboot but all that work was provided mainly by Google. We really don’t have the time or desire to spend porting coreboot for a Chromebook to a different laptop design with docs that are nearly impossible for anyone to obtain.

The mainboards will be swappable modules that will fit into various size base and display configurations.

The mainboard modules will be as open source friendly as is technically feasible.

We have been designing mainboards and single board computers since the first 8088 PC arrived as well as several other architectures. We have designed boards for PC’s, tablets, servers, supercomputers as well as industrial, medical and portable devices for over 30 years.

Plastic components will be printed on demand using high speed SLA with industrial tooling photopolymers rather than injection molding or FDM (aka cnc glue guns).

Metal components are fabricated with a combination of additive and subtractive technologies including DMLS, CNC machining and sand casting.
