Mechanical Drawings
Pin Definition (8-pin FPC)
8-pin plug-in FPC tail, 0.5 mm pitch. Pin 1 = backlight anode (LEDA), Pin 2 = GND / backlight cathode. The 4-wire SPI bus uses pins 5/6/4/8 (SDA/SCL/RS/CS). Pin 7 supplies logic power (VDD 2.8-3.2 V), Pin 3 is the active-low RESET.
| Pin No. | Symbol | Description |
|---|---|---|
| 1 | LEDA | Back-light Anode |
| 2 | GND | Power Ground / Back-light Cathode |
| 3 | RESET | Reset input pin |
| 4 | RS | Register select signal pin. L: Command H: Data |
| 5 | SDA | Serial signal input / output |
| 6 | SCL | Serial clock signal input pin |
| 7 | VDD | Power supply for interface logic circuits (2.8 V ~ 3.2 V) |
| 8 | CS | Chip select input pin |
Typical Applications
- 3D printer control screen (Creality, Prusa, Voron, Ender series)
- Arduino / ESP32 / STM32 DIY electronics and maker projects
- Industrial handheld scanner, POS and measurement HMI
- Smart home panel, thermostat and access-control display
- Smart appliance secondary display (rice cooker, air fryer, coffee machine)
Frequently Asked Questions
What are the size and resolution of FZ320-240320?
FZ320-240320 is a 3.2-inch portrait IPS TFT-LCD with 240 × 320 pixels. The base-module active area is published as 48.60 × 64.80 mm.
Which controller and interface are used?
The supplied product record identifies an ST7789P3 controller and a 4-wire SPI host interface on an 8-pin FPC.
Is capacitive touch included with every FZ320-240320 module?
No. The supplied materials show a separate capacitive-touch assembly. Confirm whether the quotation covers the base display or the touch configuration and request the matching drawing.
Do the base display and touch assembly use the same outline?
They are documented as separate configurations. Use the approved outline, FPC geometry and connector orientation for the exact quoted assembly before releasing the enclosure.
What should be verified before connecting the host?
Verify the ST7789P3 initialization sequence, voltage rails, SPI timing, pin numbering and backlight drive against the approved electrical specification.
