WT32-SC01 Plus
Also known as: WT32-SC01 Plus · ZX3D50CE02S · Wireless-Tag 3.5 inch
The pre-Guition default smart panel: a clean 3.5" IPS capacitive unit with a bezel that looks finished on a wall or desk. An openHASP officially-supported board with years of tutorials behind it.

Gotchas to know
- Only 2 MB PSRAM (N16R2) — enough for its 480x320, but heavy LVGL/ESPHome builds need care.
- No USB-UART bridge and no BOOT button: flashing is native-USB only, and recovery means shorting GPIO0 via the 7-pin MX1.25 debug connector.
- Spare GPIO comes out on an FPC connector, not headers — expansion is awkward.
- Being displaced by the half-price Guition JC3248W535; buy for the openHASP support and enclosure, not the specs.
Variants
Original WT32-SC01 (ESP32-WROVER, SPI panel) is a different, older board — most remaining stock is clones of it. The Plus (ZX3D50CE02S, ESP32-S3, 8080 bus) is the one to buy.
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.

Community guides usually go deeper than this page: pinout diagrams, wiring, library setup and copy-paste example code from people who build with these boards daily.
