Simple board to test various USB cables!
Plug in your cable to both sides and see which signals light up!
FOR CABLE USE ONLY. DO NOT EVER PLUG THIS IN TO A DEVICE, THE PINS ON ONE SIDE ARE ALL SHORTED TOGETHER AND THAT COULD BREAK IT!
Want to build your own? Take a look at the release here. There's a file called jlcpcb.zip which you can use to order bare boards or fully assembled ones from JLCPCB.
