NUC140 Learning Board

Trouble Shooting

  • PC USB port supply maximum current of 500mA
  • When shorted circuits or over-drive current from external electronic circuits or peripheral modules, PC may cut off the power of the USB port –> Just reboot the PC !
  • NUC140 chip is very hot when the learning board is running, the board may be damaged due to pin mis-connected to high voltage (>5V) –> Replace the learning board !!!
  • LCD has no display when it is cracked or damaged –> Replace the LCD !!!
  • LCD has no display when its soft cable on the back of the board was unplugged and did not reconnect properly –> User need to reconnect the LCD soft cable to the interface socket tightly
