T-Display S3 AMOLED 1.43 get it now

Overview

T-Display S3 AMOLED 1.43 is a smart display development board based on ESP32-S3R8 (16 MB Flash, 8 MB PSRAM). Equipped with a 1.43-inch SH8601 AMOLED circular display (466 × 466, QSPI), FT3168 capacitive touch, SY6970 PMU, PCF8563 RTC, TF card slot, and STEMMA QT/QWIIC interface. Supports battery voltage detection (ADC GPIO4) and 5 V/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.

FAQ

• Q. Why does my board keep failing to upload programs? A. Hold down the BOOT-0 button and try uploading again.

• Q. Why is there no serial data output from the Uart interface? A. The project defaults to USB CDC as Uart0. Set USB CDC On Boot to Disabled in Arduino Tools, or change -DARDUINO_USB_CDC_ON_BOOT=true to false in platformio.ini.
