CAD and documentation for the Expansion Bay module system in the Framework Laptop 16

Framework Laptop 16 Expansion Bay Modules

The Framework Laptop 16 has an Expansion Bay system that contains both the cooling fans and an interface for high-power, high-speed PCIe peripherals like GPUs. Expansion Bay modules can extend in both thickness and depth to accomodate higher power requirements.

There are currently two Expansion Bay modules available:

1. Expansion Bay Shell - This module has two cooling fans for the system as well as an open area in the middle that can be used for PCIe peripherals like SSDs or even additional I/O that can be exposed on the back of the system. This GitHub repository documents the mechanical and electrical specifications for the cards that can go in the Shell.
2. Graphics Module - This module is thicker and deeper, and contains a GPU card along with the heatsink for it.

Warning: the documentation here is pretty early, so there may be minor adjustments in the mechanical or electrical designs before the Framework Laptop 16 launches. We'll let you know when the design is locked for production.

Custom mechanical parts

Note that one custom part is needed for development: the threaded insert that the interposer screws into. Two pieces are needed on each Expansion Bay Module. A drawing is in the PCB Reference Design folder. You can submit a request for free samples of these for development purposes at: https://forms.gle/t4oS8qWWoaaXqVot9
