NRF9160 max current of GPIO

[McRancor]

Hi!

I'm trying to figure out what is the maximum current I can safely sink or source from NRF9160 GPIO pins.

From the spec I can see that I can expect ~10mA sink/source per GPIO line:

Which means that driving a single LED is fine, but how about more channels?

What is the total current I can drive from all GPIOs? I know nrf52 had some limits of total current which were pretty low, but I can't find such information for the nrf9160

Hello, I forwarded your question to the R&D department. Will keep you updated.

Best regards,

Hi, to ensure optimal performance, it is not recommended to sink/source more than 15 mA combined from the GPIO pins.
