What steps will reproduce the problem? 1. Go to the "Parts" window in Fritzing.

  1. Int he "Core" section, select the "LCD Display" component (it's a character LCd with 16 pins)
  2. In that component the Vdd line is always 5v, but that kind of displays are very common to be at 3,3v also (could be 3,3v or 5v)

If I add that LCD (currently only support 5V) if I connect to 3,3v power supply then schematic view in Fritzing report the Vdd line in red color indicating that there is an error.

The LCD display should have a parameter to configure if it's 3,3v or 5v.

This display works at 3,3v: https://www.sparkfun.com/products/9052 Thanks,

This issue is still there. When you hover the mouse over VDD, the info that appears says "VDD: +5V". However, when I connect a 3.3 power symbol, Fritzing does not put the line in the schematic in red. Has this functionality been removed? In any case, this issue should be moved to the parts repository. The easiest way would be to edit the description of the VDD pin to be "VDD: +5V/+3.3V"
