This box encapsulate the ST-LINK V2 mini, if you have soldered cables to it on both ends.
It is also compatible with a TTL to USB adaptor of the same size.
The box have cable retention. This is why I made it, instead of just using shrink flex.
I have used it to make a TSDZ2 programming cable, which is need if you what to change the firmware on a TSDZ2 electric bicycle motor.
I followed this guide to make the cable, but soldered cables on both ends of the ST-LINK V2 mini.
