SPWF01SA LINK, ACT, and PWR LEDs

Question asked by Aron Phillips on Jul 17, 2017

Hi all,

 

Following the schematics for the X-NUCLEO-IDW01M1 and the schematics for the STEVAL-IDW001V1 where the LEDs are connecting from the pins to ground. There is a new schematic (STEVAL-3DP001V1) that I have just encountered that has these said LEDs are connecting to the pins from a 3.3V source. Which one of these schematics are correct?

 

I am having the issue where the LINK LED goes off after it makes a successful link. This does not seem to be correct and it would seem that the link LED should light up once a successful link occurs. It would seem that the new schematic (STEVAL-3DP001V1has the LEDs correct.

 

Any insight into this issue would be greatly appreciated.
