LilyGo T Display S3 AMOLED

LilyGo T-Display S3 AMOLED (1.91")

Part of Claude Usage Stick. The AMOLED variant of the T-Display S3 — a long, narrow 240×536 RM67162 panel. One build covers every 1.91" revision: the panel variant (H712 / H713 / H705 / H681 / H717) is auto-detected at runtime by the LilyGo_AMOLED library, touch and non-touch, V1.0/V2.0/Black Shell alike.

From source, with the PlatformIO CLI:

pio run -e tdisplay-s3-amoled -t upload     # firmware

This env is for the 1.91" AMOLED variant. For the regular LCD version, use tdisplay-s3.

Controls

Input	Acts as	PIN entry	Dashboard
Physical button (GPIO 0)	Button A	Cycle the current digit	Cycle brightness
Tap the screen anywhere	Button B	Confirm digit	Force refresh

Notes

• Button B requires touch — on non-touch variants (H712 / H713) there is no Button B input, so the touch-equipped revisions are the better pick.
• During setup, the WiFi AP password is shown on the device screen.
