Add a Serial port to the LS MINI
Apparently there are two traces that have been interrupted which would allow serial port access.
These traces have been interrupted UNDER a SMD capacitor at position C54. Junker (see Yamasita's article/reference) discovered the way first
We need to fix these wires which go under C54:
Method 1: reconstruct the traces (on the backside)
This method requires absolutely no soldering.
Lay a layer of a scotch tape between holes, just not to cover them.
Use a strand of high flexible low oxygen copper wire.
- thread it through both holes,
- fix it with a scotch tape on the back side and then
- cut remainders on the front side, leaving about 2 mm.
- repeat with the second thread.
Be sure not to shorten anything else.
Method 2: Bridge the traces (on the frontside)
