Instructions for ordering
Required Files
All the required files can be found in ./OrderFiles/
- CAMFILES.zip
- WhiteJewel-all-pos.csv
- WhiteJewel.csv
Steps
- Download/clone this repo and extract it if needed.
- Go to JLCPCB.com
- Click on Add your gerber file
- Navigate to OrderFiles/CAMFILES.zip and upload it to the site. Wait till you see a preview of the board.
- You can also drag and drop
- Select the number of boards to be ordered in the PCB Qty text box.
- You can order >50 boards but the assembly process has max of 50.
- Make sure the Remove Order Number is set to YES.
- Click on the SMT Assembly slider.
- Click on Assemble Top side radio button to choose Top side assembly.
- Accept the terms and conditions and click Confirm
- Upload the BOM and the CPL files in the appropriate spots
- BOM file is called WhiteJewel.csv
- CPL file is called WhiteJewel-all-pos.csv
- Click Next
- If everything is processed successfully, The site will ask to confirm what parts to be placed. D5 and D6 are optional and can be removed by clinking the trash can icon
- After the cliking Next, the site will show you what it thnks the Assembled PCB will look like.
- Note that the site often gets the rotation of the parts wrong on the render. This is not indicative of the final board and is not an issue
- Click on Save to cart to add the order to cart.
- Get a the credit card from the Purchasing department, Apply any "Coupons" that the site lets you and complete the order.
- In addition, the following parts will have to be ordered via Digikey
- 1x 377-1807-ND per board
- 2x 609-3940-ND per board

Questions
How big is the WhiteJewel PCB?
It measures 86.9 × 32.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the WhiteJewel use?
39 parts, built around the BTS4175SGA and BSS138. 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 WhiteJewel KiCad files?
From the VRCMetalSystems/Valve-Controller repository on GitHub, at the commit this page was made from: the board is WhiteJewel.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the WhiteJewel design in my own project?
Its repository states no licence, so its author keeps all rights: ask VRCMetalSystems before reusing the design.
