Hi everyone,

On the data sheet of the nano 8, it's written :
"The Nano reset pin (RES) must be pulled up with a 10K resistor and is required to run the Nano"
But I have noticed the nano is running also without the pull up resistor?
Is it a mistake on the data sheet or will I run into problems if I leave the nano 8 without pull up resistor ?
Or there is case where you need it and other case where you don't (running motors for example )

thanks

Chris

There is an internal pullup(very weak) already on the reset pin. However its so weak it could be a problem. We recommend a 10k because its not going to accidentally get pulled down and it cuts our techsupport for reset issues alot.

Hi Nathan,

I understand, I will leave the 10K pull ups then.

thanks and best regards
