T-Display-AMOLED-Lite get it now

Overview

LILYGO T-Display-AMOLED-Lite is a compact development board based on ESP32-S3R8 (dual-core LX7, 240 MHz) featuring a 1.47-inch SH8501B0 AMOLED display (194 × 368 pixels, 450 nits). It integrates a CHSC5816 capacitive touchscreen, AXP2101 power management unit, CM32181A3OP ambient light sensor, 16 MB Flash, and 8 MB OPI PSRAM. With deep-sleep current as low as ~1.1 mA and a small form factor, it is ideal for wearable devices, portable IoT dashboards, and low-power display applications.

Note: This board does not support hardware screen rotation.

FAQ

• Q. Display shows nothing after upload? A. Ensure PSRAM is set to OPI PSRAM in Arduino IDE. In PlatformIO, verify you are using the T-Display-AMOLED environment with -DBOARD_HAS_PSRAM build flag.

• Q. Does this board support screen rotation? A. No. The 1.47-inch SH8501B0 AMOLED does not support hardware screen rotation. Software rotation may degrade performance.

• Q. Can GPIO18 be used as a general-purpose pin? A. GPIO18 is connected to the onboard RGB LED (WS2812). Avoid repurposing it unless the LED is not needed.

• Q. The touch is not responding after reset? A. Power-cycle the board fully (disconnect USB). The CHSC5816 touch controller requires proper power sequencing to initialize correctly.
