README
README.mdProject codename "remex"
remex (noun)
a primary or secondary quill feather of the wing of a bird
This is intended to be a "maker"-friendly board for the CH32V307 RISC-V microcontroller from WCH. The main selling points are gigabit Ethernet and USB-C including host support.
Status
There's a vaguely-complete layout, but actual ordering is pending final schematic review as well as further stress-testing of the chosen LiPo charger circuitry.

Questions
How big is the Remex wch PCB?
It measures 83.8 × 22.9 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Remex wch use?
102 parts, built around the CH32V307WCU6, HUSB311BLA, RTL8211F-CG and LGS5500EP. 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 Remex wch KiCad files?
From the ArcaneNibble/remex-wch repository on GitHub, at the commit this page was made from: the board is remex-wch.kicad_pcb and its schematic remex-wch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Remex wch design in my own project?
Its repository publishes it under the 0BSD licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
