DockFrame is a modular USB Type-C hub built around the Framework Expansion Card slot standard. It gives the cards you already own a home on your desk, and adds what no other dock can: Tool Cards that turn the slots into bench instruments, all within reach of one cable. It works with any Framework laptop or desktop, or any USB Type-C host.

Slot in the Multimeter Card and the hub reads volts, amps, and ohms, isolated from your laptop. Slot in the Power Supply Card and you get a programmable bench supply that runs off USB PD. Slot in the BreadBoard Card and you always have a dev board on hand. And the card most of you asked for, the Mini Hub Card, adds four more high-speed ports of its own.

A Dock and a Bench, in One<br>Keep it on the desk as your everyday dock, and reach for the same unit when a project needs measuring or powering. Your spare Framework cards come back into use, and tools stop going missing. It handles everyday docking, bench bring-up, lab work, and field repairs.

The open slot standard makes DockFrame extendable. Tool Cards talk to our custom web apps, with nothing to install, live charts, and CSV export. Design your own card, or build a host app over USB serial, Wi-Fi, Bluetooth, ESP-NOW, and the other protocols the onboard MCUs support. We are keeping it open source so a community can improve and expand it.

BreadBoard Card

USB Type-C carrier for the Seeed Studio XIAO ESP32-C5; takes the full XIAO series and any form-factor-compatible board

Built-in USB Type-C plug plus pass-through, with 8 rows of 0.1 in headers for breadboard insertion

Regulated 3.3 V rail with load switches, resettable fuse, and ESD protection

Each card is 60 x 30 mm (2.36 x 1.18 in), with height around 7 mm (0.28 in) depending on the card.

Open Source

We strongly believe in the right to repair, which is why DockFrame is modular, fixable, and built to last. It is developed in the open, but the design files are not public yet. Once the campaign ends, we open everything: PCB schematics and layouts, the firmware on each MCU, the browser apps, and the FreeCAD case files with STEP and STL exports, so you can print your own enclosure. The hardware will be licensed under CERN-OHL-S, the product certified through the Open Source Hardware Association, and the firmware released under the MIT license. The full release publishes on our GitHub page when the campaign ends.
