WROVER-KIT resistances / inductors

[Driver55]

in relation to the WROVER-KIT:
Can anyone tell me what kind of resistances are those in series to the signals, marked with (0R 1%).
Are they inductors to reduce disturbances ?? ..
If yes ....
which model ??
what value of inductance ??

Thanks in advance

Hi Driver,

"0R 1%" is shorthand for a zero ohm resistor, 1% tolerance.

These essentially do nothing in the design (they're the equivalent of a wire straight through), except that you can remove them from the PCB to open the connection and you can replace them with a higher value resistor if you need to create a series resistance.

You'll notice that some are marked "0R 1% (NC)". The NC is convention for "No Connect" (some schematics use NP for Not Placed or DNP for Do Not Place). This means no resistor is placed here by default (but, similarly, the pads are available on the PCB if someone needs to add a connection here without changing the PCB design.)

Thanks Angus.
