Expansion Cards are custom form factor USB-C adapters that enable customizable and hot-swappable I/O on Framework laptops. The cards lock into Expansion Card Bays on Framework Laptop 13 and Framework Laptop 16.
Expansion Cards are standard USB-C adapters, so they can be used with any host device that supports the applicable parts of the USB-C specification. 1
Framework published electrical and mechanical templates on their GitHub to enable third-party developers to design and manufacture their own cards. 2 Some examples are below:
