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.
