nwt1976 Posted June 27, 2018 Report Share Posted June 27, 2018 Im installing pressure sensors using expansion connector but having problems with 5 volt output. Possible short circuit? How many sensors can you run off one 5V output pin? Quote Link to comment Share on other sites More sharing options...

Possible short circuit? How many sensors can you run off one 5V output pin? Its either 4 or 500mA from memory so you will have a hard time overloading it. Most common pressure sensors are about 10mA, so should have enough juice to power at least 30. So most likely a short. You can view the 5V output on the runtimes screen, so you can watch that while pluging in various sensors to find where the problem is.

Brad Burnett Posted June 27, 2018 Report Share Posted June 27, 2018 Recently had a oil pressure sensor short internally. Being able to view the 5v rail status in the runtime list is excellent. Quote Link to comment Share on other sites More sharing options...
