pinout check nrf52832

[MGdeGroot]

Hi,

I have a question about my schematic. In the datasheet I've read that it doesn't matter which pin is used for several pheripherals like SPI.

So does this means that the following schematic is correct?

Hi Mark,

Yes, you can configure any GPIO pins for use with any peripheral. Just make sure you follow the GPIO usage restrictions guidelines, mentioned in the documentation.

Best regards,

Jørgen

Thanks Jørgen!

Does Low drive, low frequency I/O only mean I can't use it for SPI?

The same section in the nRF52840 specification says that low frequency I/O means less than 10kHz. I would guess that the restriction is the same for nRF52832 as well.

Yes, it is not recommended to use these pins for SPI while radio is active. Take a look at this thread.
