External reset switch

[Juniorprogrammer]

Hi,

I have added an external reset switch on my custom board. Maybe a stupid question, but do I need a pull-up resistor? Because in de schematics of the nrf52840 dk I didn't see an pull up resistor.

Kind regards,

JP

There's an internal pull up resistor in the RESET pin, so just pull it to ground with a switch.
