The Industrial Raspberry Pi Forum

Hi, as shown below, both PWR LEDs turned red after being green for a few hours. It happened when I was going through this tutorial:
https://www.instructables.com/id/Read-a ... pberry-Pi/
Is there a common reason this would happen? No wire connections were changed, or at least, they were the same as they had been for weeks with full connections and no issues. In putty using the "piTest -d" command, the module went from "present" to "present but not configured" to "not present, data not available", all in the same session (shown in the image).


This was rather unexpected, so help is appreciated!

Dear HYPERH2, unfortunately the pictures are not visible. The link you posted shows a tutorial for a RaspberryPi module which may work. So the tutorial worked for you and after a while the RevPi seams to work suspicious like the piTest -d results? Or did this never work as expected? Then there is a classic RevPi != RaspberryPi situation you know As there are for example no digital IOs available as they are with the RaspberryPi and also the serial interface, etc.
