Why 3.5-inch is the MCU sweet spot
At 320×480 a full RGB565 frame is 300 KB, small enough for a driver IC to hold in its own memory. The microcontroller only sends changed regions, so even a mid-range MCU can run a responsive LVGL interface over SPI.
ST7796S or ILI9488?
| ST7796S | ILI9488 |
|---|---|---|
SPI pixel format | RGB565 (2 bytes) | RGB666 only (3 bytes) |
Full-frame SPI transfer | 307 KB | 461 KB |
Typical SPI frame rate @40 MHz | ~16 fps | ~11 fps |
8080 parallel | Yes | Yes |
For SPI designs we recommend ST7796S. Keep ILI9488 for 8080-parallel designs or existing products.
Touch options
- Resistive (XPT2046 over SPI): works with gloves and styluses and costs less. It needs calibration and feels soft.
- Capacitive (FT6336 or GT911 over I2C): multi-touch and a glass front, which suits consumer-grade products.
Typical applications
Handheld test instruments, 3D printer controllers, smart thermostats, access-control readers and battery-powered IoT devices.
Frequently asked questions
What driver IC does a 3.5-inch TFT use?
Most 320×480 modules use ST7796S or ILI9488. Some low-cost modules use ILI9486. Always confirm the driver from the datasheet, because init sequences are not interchangeable.
Can I run a 3.5-inch display over SPI at a good frame rate?
With an ST7796S at 40–80 MHz SPI and partial updates, LVGL UIs feel smooth. Full-screen animations are limited to roughly 15–25 fps, so use 8080 parallel if you need video-like refresh.
Is resistive or capacitive touch better for a 3.5-inch display?
Capacitive is better for consumer products and multi-touch. Resistive suits industrial use with gloves or a stylus and is cheaper.
