WT32-SC01

3.5" 320x480 ST7796 over SPI with FT6336U capacitive touch.

Building for it

A project is made for one toolchain, picked when you start it. All four can drive this board:

At a glance

Display pins

ST7796 / ST7796S on SPI (4-wire serial): SPI clock 40 MHz, host VSPI, BGR colour order, inversion off.

Touch pins

FT6236 / FT6336U: I2C address 0x38, 400 kHz.

Designing for it in LCD Wizard

• Choose WT32-SC01 on the Hardware tab (or use the button above) and every pin on this page is filled in. The export writes the sketch, lcd_pins.h, the LovyanGFX configuration, lv_conf.h and platformio.ini - a project that builds for this board as it comes.
• The FT6236 / FT6336U is capacitive and needs no calibration. The firmware resets it and checks it answers on every boot.
• The backlight is dimmable: give a slider or a button a Set backlight action.
• With PSRAM the LVGL memory pool can live there, leaving internal RAM for everything else.
• Screens are designed for 320 x 480 px in either orientation, with LVGL 9 or LVGL 8.

The parts

ST7796 / ST7796S. The usual 4.0" 320x480 controller. Faster than ILI9488 over SPI (true RGB565).

FT6236 / FT6336U. Register-compatible with the FT6206. Very common on 2.8"-3.5" capacitive TFTs.

ESP32 (WROOM / WROVER). No native RGB parallel peripheral - use SPI or an 8/16-bit i80 bus.

LovyanGFX. Widest panel and bus coverage, DMA on ESP32. Configured with a C++ config class.

The pinout on one page

Every pin above, laid out to print and keep beside the bench. Generated from this preset, so it says exactly what the designer writes into lcd_pins.h.

From the people who made it

The board’s own documentation. Pinouts on vendor pages do sometimes disagree with the hardware in front of you - where this page and that one differ, trust your board and tell us.
