Input pin takes allot of current

[Nadeem]

Dear All,

I have a simple push-button.

Vcc-100k resistor ->> Push button --> Ground.

When  I measure the current consumption when the button is pressed i get around 230 uA.. This is very high for my application is the button is used allot.

What's the max resistor can I use to reduce the consumption.

thanking you,

Hi,

If you use nRF52832 and configure GPIO with pull-up , then its pull-up resistor (typical 13k) will consume current too.
