Raw Blame History

Guition ESP32-S3 4.3" 480x272 Capacitive Touch Display

Sold under several names (Guition JC4827W543, Sunton ESP32-8048S043, and similar).

Hardware

  • MCU: ESP32-S3, 8MB PSRAM
  • Display: 4.3", 480x272, New Vision NV3041A over QSPI (1 clock, 1 CS, 4 data lines, no HSYNC/VSYNC/DE)
  • Touch: GT911 capacitive, I2C
  • Audio: NS4168 I2S speaker amp only - no codec, no onboard mic

Pins

Function Pins
QSPI LCD (NV3041A) CS=45, SCLK=47, D0=21, D1=48, D2=40, D3=39, Backlight=1. Clock 32MHz.
Touch I2C (GT911) SDA=8, SCL=4, INT=3, RST=38, address 0x5D
Audio I2S (NS4168) BCK=42, WS=2, DATA=41
SD (SD_MMC, 1-bit) CLK=12, CMD=11, D0=13. DAT3 (GPIO10) is wired but unused in code.
SD (SPI, alternative) CS=10, MOSI=11, CLK=12, MISO=13 - same physical pins as SD_MMC above, untested

Build options

The lcd-test/lcd-test-gfx examples require:

  • PSRAM=opi - the board's default FQBN has PSRAM disabled
  • CDCOnBoot=cdc - required for Serial output over the native USB port; without it Serial routes to the UART0 pins instead

Example FQBN: esp32:esp32:esp32s3:CDCOnBoot=cdc,PSRAM=opi

Examples

  • lcd-test-gfx - RGB/greyscale color diagnostic, tap to switch tests. Uses Arduino_GFX's Arduino_NV3041A driver for the display and TAMC_GT911 for touch.
  • lcd-test - same diagnostic, built on TinyGPU's NV3041ADriver and TouchDriverGT911 instead.
  • audio-out - sine wave playback through the NS4168 amp via I2SStream.
  • sdmmc-test - brings up the microSD card over SD_MMC in 1-bit mode, writes/reads a test file, lists the root directory.
  • sd-test - the same card over plain SPI (SD.h) instead of SD_MMC.
  • player-sdmmc - MP3 playback off the microSD card (AudioSourceSDMMC + MP3DecoderHelix) through the NS4168 amp.

Not included: audio-in (no onboard mic) and led-test (no RGB LED on this board).

TinyGPU Support

This board's QSPI LCD and GT911 touch controller are supported in TinyGPU via:

  • TinyGPU/DisplayDriverQSPI.h - DisplayDriverQSPI<RGB_T>, a base class for QSPI TFT/AMOLED controllers (NV3041A, ST77916, CO5300, SH8601, AXS15231B, ...) wrapping ESP-IDF's esp_lcd_new_panel_io_spi() (quad mode). NV3041ADriver is the concrete NV3041A subclass.
  • TinyGPU/TouchDriver.h - TouchDriverGT911. Reports up to 5 simultaneous touches; getSecondPoint() is a real second contact, not a stub.
