Guition JC4827W543 (4.3" ESP32-S3)
Also known as: JC4827W543 · JC4827W543C · Guition 4.3 inch ESP32-S3
A 4.3" capacitive touch panel on an ESP32-S3 for around $12 — the successor to Sunton's 4827S043 and one of the cheapest routes to a decent-sized LVGL UI. Officially supported by openHASP.

Gotchas to know
- Only 4 MB flash (N4R8) — large LVGL/ESPHome builds get tight; there is no 16 MB SKU.
- The NV3041A needs colour-invert + byte-swap settings, and only 0°/180° rotation works.
- In Arduino_GFX, SD-card and touch access can break after a display flush (shared bus quirk) — order operations carefully.
- 480x272 is a low resolution for 4.3" — fine for control panels, chunky for dashboards.
Variants
JC4827W543 N/R/C (none/resistive/capacitive touch). Successor to the Sunton ESP32-4827S043; same 480x272 panel class but QSPI instead of RGB, freeing GPIO.
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.
