Required

Apply a regulated 2.8 V rail to all VCC contacts. Use a 2.8 V parallel host or level translators for the bus and control lines. Connect independent backlight current sinks and leave the touch electrodes open for the display test.

Bench checks

  • Verify that every VCC contact has the same rail and that the display bus changes direction only for read cycles.
  • Run the Newhaven HX8347 initialization example and verify known solid colors. If the display stays white, verify the module revision and the non-sequential mapping of DB4–DB7.
