There's also voltage isolation accessory "B-STLINK-VOLT"
- STDC14: 14 pin main connector. 7x2, 1.27 mm pitch
- You can snap off the top and bottom pins to mechanically and electrically convert to MIPI10 if you really don't need the higher performance
- MIPI10: STLinkV2 connector. 5x2, 1.27 mm pitch
TLDR: I should have used TC2030-CTX-STDC14, but was sent TC2030-CTX. I can snap STLinkV3 pins to make them compatible if in a bind
