(and you can't stop me)
This is my random collection of adapters and PCBs designed to make everything in my lab USB-C compatible.
USB type B replacement
Drop-in replacement for the old classic USB type B connector. Includes a 3d-printed plastic part to match the connector shape.
Barrel Jack replacement
Drop-in replacement for the good old 5.5mm, barrel jack.
- Mostly fits in the existing footprints.
- Set to 12V/3A by default.
- Puts the USB-C connector at the correct height by stacking three PCBs together.
- Allows for both positive and negative polarity, depending on the bottom PCB used.
- Voltage and current negotiation parameters can be changed by modifying resistor straps.
- Subject to limitations of USB-C PD - for example, an Apple charger can't output 12V.
Isolated UART, 1.8-5.5V
Serial port adapter with two control lines (RTS and DTR), 1.5kV isolated. The initial use was programming ESP8266 but comes useful in many other scenarios.
3Dconnexion CadMouse
Replacement PCB for the 3Dconnexion CadMouse. Originally Micro USB. Requires some milling to fit the new PCB.
3Dconnexion SpaceMouse
Replacement PCB for the 3Dconnexion SpaceMouse. Originally Micro USB. Includes a 3D-printed plastic part.
FAQ

Q: What's the USB connector on these designs?
A: My current goto connector is GCT USB4105-GF-A. It's cheap and good. The WE equivalent is 629722000214. Other manufacturers most probably have equivalent connectors - this is the de-facto standard footprint for USB-C 2.0. -

Questions
How big is the Brother usbc PCB?
It measures 59 × 20 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Brother usbc use?
29 parts, built around the TPS25730DREFR, TVS2200DRV and USB4125-GF-A. 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 Brother usbc KiCad files?
From the kosma/usb-c-everywhere repository on GitHub, at the commit this page was made from: the board is usb-c-barreljack/brother-usbc.kicad_pcb and its schematic usb-b2c/usb-b2c.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Brother usbc design in my own project?
Its repository states no licence, so its author keeps all rights: ask kosma before reusing the design.
