Hi,
we ordered 2 Adafruit 3.5" TFT LCD Displays. We attach Display 1 to Arduino Mega and it's working well. When we attached Display 2 on same, Arduino drives reset.
Then we only powering the Display with 5 VDC and figuered out, that Display 2 break 5 Ampere fuse on Power Supply.
In the Attached PDF an overview of our findings. We upload also the photos with a better resoluton.
Many thanks for any comment or replacement.

Re: Adafruit Display 3.5" TFT LCD
Display 1 appears to have headers soldered to the display while Display 2 has wires directly soldered. Where do those wires that are soldered on Display 2 go?

Re: Adafruit Display 3.5" TFT LCD
Display 2 has cable soldered which have a connector on other side, and they plugged in directly to Arduino.
We soldered cables before we test Display 2 --> but was not overheated during soldering !
As you can see, resistance between 5V and GND on Display 1 and Display 2 is almost same, so soldering/cables is/are fine...

Re: Adafruit Display 3.5" TFT LCD
They appear to be terminated in some kind of female connector. These won't plug directly into an Arduino. Are there more cables or other hardware involved?Display 2 has cable soldered which have a connector on other side, and they plugged in directly to Arduino.
