I used before instance SPIM2, because SDK was limited, I have downloaded the new SDK and will try with SPIM3. I asked about the max speed, because I read on the forums about it.

I will late you know tomorrow, thank you.

Yes, it seems like you have Engineering C / Rev 1. Which instance are you using? SPIM3 is the only instance that supports higher than 8 Mbps.

Hi,

Thank you for the info, It looks like, I have the version of the mcu nrf52840QIAAC01805AA on dev board- it looks like engineering C.

Is it correct?

Hi,

Which nRF52840 revision are you testing with? 16 and 32 MHz should be working for engineering B and later, including the production revision 1. See this thread.
