title: SHARP LS037V7DW01 TFT-LCD panel

description: |
  This panel can have zero to five GPIOs to configure to change configuration
  between QVGA and VGA mode and the scan direction. As these pins can be also
  configured with external pulls, all the GPIOs are considered optional with holes
  in the array.
