LilyGo T-Display-S3 AMOLED
Also known as: T-Display-S3 AMOLED · LilyGo AMOLED 1.91
The T-Display-S3's premium sibling: a punchy 240x536 AMOLED strip with true blacks and high contrast, ideal for tickers, gauges and pocket UIs where the wide-format IPS looks washed out.

Gotchas to know
- QSPI AMOLED means TFT_eSPI is out — use Arduino_GFX or LilyGo's own examples.
- AMOLED burn-in with static elements; rotate content or dim aggressively.
- Touch vs non-touch SKUs (and a Plus revision with more GPIO/Qwiic) get conflated in listings — check which you're buying.
- Usual LilyGo caveats: docs are example dumps, and SKUs cycle in and out of stock.
Variants
Family: AMOLED (1.91"), AMOLED Plus (touch + Qwiic + 18 GPIO), Lite, and the dual-screen DS. The 2.33" T-Display-S3 Pro and 3.4" T-Display-S3 Long are separate 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.
Resources
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.
