Sunton ESP32-8048S070 (7" RGB panel)
Also known as: ESP32-8048S070 · Sunton 7 inch ESP32-S3 · 8048S070C
The cheapest way to a 7" touch dashboard: ESP32-S3 N16R8 driving an 800x480 parallel-RGB panel with GT911 capacitive touch for ~$22. The default budget pick for Home Assistant wall dashboards.

Gotchas to know
- The 800x480 framebuffer must live in PSRAM — expect flicker/tearing under Wi-Fi load unless you use LVGL bounce buffers / XIP-from-PSRAM tuning.
- The RGB bus consumes nearly every GPIO; almost no pins left for sensors (use I2C on the shared connector).
- Board revisions v1.1 vs v1.3 need different init code, and pinouts published for the 4.3" (8048S043) are wrong for the 7".
- Check the panel SKU: sibling 4827S043 is a TN panel with narrow viewing angles; for a wall panel you want this IPS 800x480 class.
Variants
Sunton 8048 family: S043 (4.3"), S050 (5"), S070 (7") — all 800x480 RGB on ESP32-S3 N16R8, N/R/C touch suffixes. The 4827S043 (480x272 TN) is the cheaper, worse sibling.
The ESP32-S3 inside

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. This board has few free pins (see above) — favour I2C sensors, which share 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.
