T-Display S3 AMOLED 1.64

Overview

T-Display S3 AMOLED 1.64 is a high-performance IoT development board based on ESP32-S3R8 (16 MB Flash, 8 MB PSRAM), integrating 2.4 GHz Wi-Fi and Bluetooth 5.0 LE. Equipped with a 1.64-inch ICMA3311 AMOLED display (280 × 456, QSPI), FT3168 capacitive touch, SY6970 charger, PCF8563 RTC, TF card, and 2 × STEMMA QT/QWIIC interfaces. Supports battery voltage detection (ADC GPIO4) and 5 V/500 mA USB charging. Suitable for smart wearables, embedded GUI, and industrial control in a compact 28 × 42 × 11 mm form factor.

The output waveform of the SY6970 charger will be very unstable when powered by 5V without a battery. Connect a battery for use, or use software to disable the battery channel.
