Hi,
I have a nRF52840 Preview Development Kit. I studied your manual, but I didn't quite understand if this is possible or not?
- I would like to debug (therefore I need the interface MCU). So far so good.
- My periphery of the nRF52 is 1.8V (does not work with >1.9V, I2C on P0.26 and P0.27)
- Is there a way that I can debug (USB plugged in in J2 connector for debugging and as power supply for the interface MCU) and I have the nRF (Vdd) supplied with an external 1.8V supply e.g. on P21?
- Which SW has to be set in which position?
Thank you for any help! Reto
