veroxzik/usb-boards2A collection of USB boards.
Usbc jstxh mini is an open-source printed circuit board by veroxzik, from the veroxzik/usb-boards repository on GitHub, published under the MIT licence. It is a 2-layer board of 45 × 15 mm with 6 parts on 6 nets, routed with 35 tracks and 0 vias.
It is built around the 918-418K2022Y40000. Its parts include 2 resistors and 2 connectors.
This is a simple board to convert JST-XH pinout used by Yuancon controllers to a USB-C socket.
It is modeled off the size, shape, and hole placement of newer Yuancon USB-C controllers.
This board uses a straight JST-XH and a straight USB-C connector.
| Component | Qty | LCSC Part Number |
|---|---|---|
| USB-C Connector | 1 | C168704 |
| JST-XH 4 pin | 1 | C161871 (Official) OR C37815 (Knockoff) |
| 5.1kOhm 0805 | 1 | C27834 |
The board size is 45mm x 15mm. There are two M3 (4-40) holes 40mm apart, centered about the USB connector.
For the JST-XH:
| Pin # | Signal |
|---|---|
| 1 | +5V |
| 2 | D- |
| 3 | D+ |
| 4 | GND |
This pinout is the mirror of what is on the Yuancon, as the stock cable flips the pinout.
This USB connector only supports USB 2.0. If using a USB-C to USB-C cable, the 5.1kOhm restors must be used.
They can be omitted for USB-A to USB-C cables.

From the veroxzik/usb-boards repository on GitHub, at the commit this page was made from: the board is usbc-jstxh-mini/usbc-jstxh-mini.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
