README
README.mdframework CAN Interface
USB to CAN device that fits in a Framework laptop expansion card.
Hardware
The USB to CAN device is based on the STM32G431 microcontroller and TCAN1042 CAN transceiver.
The hardware is inspired by (but not a direct clone of) the Canable 2.0.
It includes a removeable push-in spring connector for easy wiring to any CAN bus.
Software support
Supports CANFD (Up to 5Mbaud) with slcan firmware, and socketcan on Linux with candlelight firmware.
For software support, see the "Software Support" section at canable.io

Questions
How big is the Framework usb2can PCB?
It measures 26 × 25.6 mm and has 4 copper layers, 0.8 mm thick.
What parts does the Framework usb2can use?
39 parts, built around the TCAN1042HGVDQ1 and AP2112K-3.3. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Framework usb2can KiCad files?
From the JackToaster/framework-usb2can repository on GitHub, at the commit this page was made from: the board is pcb.kicad_pcb and its schematic pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Framework usb2can design in my own project?
Its repository states no licence, so its author keeps all rights: ask JackToaster before reusing the design.
