Here is my EasyEDA project: Framework Laptop 40-pin to 30-pin eDP monitor adapter - EasyEDA open source hardware lab
You should be able to use that to directly order from JLCPCB by following some basic “how-to” pages on how to get from an EasyEDA design to a JLCPCB order, JLCPCB will do the SMD components for you as well. 5 boards cost $20 delivered to the UK with one of their regular coupons.
You are obviously responsible for your own DIY adventures. If the pins and voltages match up you should be golden, but if you aren’t prepared to eat the cost of a dead board you probably shouldn’t be mucking around with DIY-ing such things.
