Re: PiRLP Suddenly Not Working
David Cameron - IRLP
Under normal circumstances, with all LEDS lit, the board draws less than 80mA at 3.3V. Without any LEDs it is in the order of 2mA.toggle quoted messageShow quoted text
Can you take a picture of the mod you did to bring 3.3V? Maybe I will see the issue. Both the top and bottom of the board.
There are lots of locations where a short could be in the board. A cold joint would never cause a short, it would cause it to be open.
I would look more carefully at the GPIO cable as it is more suspect.
Also, check the resistance to ground from the 3.3V jumper to the board ground.
The other thing to do is try to power on the system, and feel around the chips on the IRLP board for something getting hot. Nothing should be mildly warm.
