Sometimes, RX-TX transceiver interconnections aren’t well defined about who is the module that transmits or receives. This is due to lags in design requirements or information missing.
The resistor shunts will provide a platform to intercross RX to TX connections by rotating these resistors 90 degrees in a rework.
For this reason one of these resistors should rotate 180 degrees in layout, and both resistors should be placed one besides the other, maintaining same air gap between resistors’ pads, therefore, preserving its schematic connections.
CAD should look similar to this:
As a final result, in case of misconnection, a quick rework consisting in 90 degrees resistors’ rotation will fix the issue.
