So it does not provide testpoints for monitoring USB Type-C signals. USB C-thru provides test points for VBus, CC1, CC2/VConn, SBU and GND. Also has a VBus voltage divider for automating measurement. We initially did look at Twinky when we were developing our own protocol analyzer, the design is very complex. So we designed our own protocol analyzer. That is also soon to launch on https://www.crowdsupply.com/goarks/usb-type-c-pd-analyzer. Thank you.
