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
Method 1: reconstruct the traces (on the backside)
Method 2: Bridge the traces (on the frontside)
