Adafruit Display 3.5" TFT LCD

Post by olbi »

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.

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?

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...

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?
