Guition JC3248W535 (3.5" ESP32-S3)
Also known as: JC3248W535 · JC3248W535EN · Guition 3.5 inch ESP32-S3 display
The 'better CYD': a 3.5" IPS with capacitive touch, an ESP32-S3 with 16MB flash / 8MB PSRAM and a battery-charge circuit, for barely more than the original resistive CYD. The QSPI display leaves real GPIO free.

Gotchas to know
- The AXS15231B QSPI panel only works in LVGL full-refresh mode (partial/direct render is broken), and there is no hardware rotation — plan for 0°/180° in software.
- TFT_eSPI can't drive QSPI panels; use Arduino_GFX 1.5.0+ or ESP-IDF esp_lcd.
- Some batches ignore window-address (0x2A/0x2B) commands — suspected non-genuine AXS15231B silicon; stick to full-frame updates.
- openHASP support is still unmerged; ESPHome works via the mipi_spi component's JC3248W535 preset.
Variants
Suffix N/R/C = no touch / resistive / capacitive; the capacitive JC3248W535(EN) is the one everyone means. Guition also does the smaller JC2432W328 (2.8") and larger RGB/P4 boards.
The ESP32-S3 inside
This board is built on the ESP32-S3 . See the SoC page for the full peripheral, GPIO and security details.

Adding sensors?
Presence radars, climate, CO2, energy — the sensor comparison table covers what people actually wire to these boards, with ESPHome support status and clone-risk ratings per part. Radars want a hardware UART; I2C sensors chain on two pins.
