I need to decide which pins I should use for 3 LEDs (5 mA each).
The "recommended usage" column in the documentation for the nRF52840 in Table 1 Pin assignements
mentions "Standard drive, low frequency I/O only" for many pins. But it does not distinguish between "drive strength" and "frequency" here.
I'm aware about the differences between standard and high drive, and also that I should not use these pins for higher frequencies > 10 kHz.
( I will use RF radio )
But my problem is simply that I'm not sure how to read "Standard drive, low frequency I/O only"
Should it be read as "Standard drive only OR low frequency I/O only" ?
I.e. should I not use these pins for my (more or less static) LEDs, if I want to configure High-Drive ?
