Pull up resistor for low power usage

RE: Pull up resistor for low power usage

Hi Sam,

We don't have anything specified for this, but maybe this ticket can help you. Also, using 1M resistor should also help.

You can probably go higher than that too, but then the circuit is more exposed to noise, and it is difficult to say anything about until you have started on the actual PCB design.

Priyanka sorry I think there might be some confusion related to the question. We would like to know what the maximum resistance value we are able to use for an input pin is?

Hi Sam,

We have a 13.5k internal pull-up resistance. So maybe you could configure the GPIO to enable the internal pull up, so there is no need for an external pull up.

Hi Sam,

Extremely sorry for the delay. Most of the experts are on vacation since it's the holiday week in Norway. I will get back to you as soon as possible. Thank you for your patience.

Priyanka,

This is the schematic with a 100k pull up resistor.

Hi Stefan,

Is it possible to attach the schematic of the custom board?

Best Regards,
