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.
