The Embedded Controller is the chip responsible for low-level tasks: battery charging limits, fan speed curves, keyboard matrices, and power-button LEDs. Framework uses an open-source EC firmware based on Chromium EC. The schematics show exactly which pins on the EC control which hardware features, a goldmine for developers looking to modify the physical behavior of their laptop.
Furthermore, Framework releases these schematics under Creative Commons or open-source-friendly terms for non-commercial or maker use. This empowers the community to build custom hardware—such as standalone cases that turn a spare Framework Mainboard into a desktop PC or a home server. How to Access Official Framework Schematics
: Detailed mainboard schematics and assembly drawings are provided to professional repair businesses upon request to support component-level repair. RISC-V Ecosystem : In partnership with DeepComputing framework laptop schematics
– Yes, essential for component-level repair.
The availability of schematics sits at the heart of the Right-to-Repair movement. Framework’s journey with this has been a public and instructional case study. The Embedded Controller is the chip responsible for
One of Framework’s unique features is its modular Expansion Card slots. The schematics map out the internal proprietary-free design of these bays. They show how the internal PCIe, USB4, or DisplayPort signals travel directly from the CPU/Chipset to the physical interface slots, allowing hobbyists to design custom expansion cards (like micro-projectors, SDR radios, or custom ports). 3. Embedded Controller (EC) Pinouts
Here is your guide to understanding what’s available, where to find it, and why some parts remain hidden. 1. The Two-Tier Access Model RISC-V Ecosystem : In partnership with DeepComputing –
Laptop motherboards rely on a strict power-on sequence. Voltage from the battery or USB-C charger is stepped down into various "power rails" (e.g., +3VALW for always-on 3.3 volts, +5V for USB devices, and +VCC_CORE for the processor). Framework schematics clearly label these rails, allowing you to use a multimeter to check if the board is generating the necessary voltages to boot. Identify Components with Reference Designators Every component on a Framework board has a unique label: stands for Resistor (e.g., R1202) C stands for Capacitor (e.g., C3405) U stands for Integrated Circuit/Chips (e.g., U4001) Q stands for Transistor/Mosfet (e.g., Q2201)
This is crucial for identifying "hidden" traces or finding alternative solder points if a pad is ripped off the board during a bad repair. C. 2D and 3D CAD Files
Framework completely upended this status quo. By releasing highly detailed circuit schematics and board views for its devices, the company shifted the balance of power back to the consumer. For engineers, repair technicians, and hardware enthusiasts, Framework Laptop schematics are more than just repair guides—they are a masterclass in modern laptop design and a blueprint for the open-source hardware movement.
