xl97:
is the cap even needed if your circuit has one already? (ie: an Arduino compatible pcb with DTR breakout already...etc).. then only a 'jumper' yes?
It's actually mention earlier in this thread by CrossRoads that if you add a cap on the CP2102 as well as have one on the board the results may be undesirable.
So no, it's not needed and yes, just a jumper.
