IO0 and IO2 pullup / pulldown resistors
Posted: Fri Dec 15, 2017 9:32 am
Hi,
On Espressif's devkit IO0 and IO2 pullup / pulldown resistors are not present.
When designing my own board with WROOM32 module can I omit them entirely?
Another question is about the capacitor from the EN pin to ground. On some designs it is not present.
I suppose it is to introduce a delay to EN going high on power up. How essential is it?
Thanks in advance, cheers
