Guition JC2432W328 (capacitive CYD)
Also known as: JC2432W328 · JC2432W328C · capacitive Cheap Yellow Display
Fixes the classic CYD's biggest regret — resistive touch — for about $3 more: same 2.8" 240x320 class, but capacitive CST820 touch and USB-C. Increasingly what people mean when they say 'CYD' in 2026.

Gotchas to know
- NOT pin-compatible with the classic ESP32-2432S028R — sketches and firmware images need this board's pin map (community Marauder/CYD forks exist specifically for it).
- ST7789 panel needs display inversion vs the ILI9341 configs floating around.
- Classic-ESP32 SoC and no PSRAM — fine for dashboards, limiting for heavy LVGL.
- Clone-batch variability applies here too; verify driver/touch ICs on arrival.
Variants
JC2432W328 C = capacitive (the point of buying it); an R resistive variant exists. Part of the wider Guition JC family (JC3248W535 3.5", JC8048W550 5").
The ESP32 inside
This board is built on the ESP32 (ESP32 (classic)). 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.
