# Selected exact parts and manufacturer sources

These are the BOM selections embedded in the KiCad schematic. Availability,
life-cycle status, distributor stock and the display's orderable configuration
suffix were not verified; no purchasing claim is made.

## Display dimensional and pinout source facts used

- Resolution 800 x 480; SSD1963 controller; landscape module.
- Module outer envelope 180 x 100 mm; documented maximum thickness 12.8 mm.
- Active area 154.08 x 85.92 mm.
- Four 3.2 mm mounting holes on 174 x 98 mm centres.
- Maximum module current used for the budget: 480 mA at 5 V.
- Pin map: 1 GND, 2 5V, 3 /CS, 4 D/C, 5 /RD, 6 /WR, 7 RESET,
  8 TE, 9-32 DB0-DB23, 33-38 touch-related, 39 BL_ON/OFF/PWM, 40 NC.

The base MPN does not encode every selectable factory interface/no-touch option.
An order must quote and confirm the exact 5 V, 8-bit 8080, no-touch, pin-header
configuration with EastRising before procurement. That is an unresolved
ordering assumption, not an invented suffix.
