T-Display S3 AMOLED 1.75 get it now

Overview

T-Display S3 AMOLED 1.75 is a highly integrated development board based on ESP32-S3R8 (16 MB Flash, 8 MB PSRAM). Equipped with a 1.75-inch SH8601 AMOLED display (280 × 456, QSPI), FT3168 capacitive touch, SY6970 PMU, PCF8563 RTC, TF card slot, and dual STEMMA QT/QWIIC interfaces. Supports battery voltage detection and 5V/500 mA USB charging. Suitable for smart wearables, embedded GUI, and IoT terminals in a compact 45 × 45 × 11 mm form factor.

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