Missing capacitors on voltage regulator? #64

Closed levpopov closed 1 year ago

levpopov commented 1 year ago

AP2112 LDO datasheet[1] specifies 1uF capacitors on VIN and VOUT but these are missing in the nrfmicro schematic. Is this intentional?

PS thank you for this repo, it's a great resource.

No space, also we have a bunch on the module, it's in the FAQ. If you have space use 10uF before and 4.7uF after. We don't have much pulse before and we have 4.7 uF after on the module.

Ah, thanks for explaining
