=== PL bank 34 ===
Routing implemented on Bora SoM allows the use of bank 34's signals as differential pairs as well as single-ended lines. Signals are grouped as denoted by the following table that details routing rules on Bora module. No carrier board guidelines can be provided, because these are application-dependent.
Pairs are highlighted with different colors. When used as differential pairs, differential impedence is 100 Ohm. When used as single-ended signals, impedence is 50 Ohm.
