T-Display S3 Pro get it now

Overview

T-Display S3 Pro is a high-performance development board based on ESP32-S3R8 (16 MB Flash, 8 MB OPI PSRAM). Features a 2.2-inch ST7789V2 IPS display (222 × 480), CST816S capacitive touch, SY6970 PMU (1.5 A charging, OTG output), LTR553 ambient light/proximity sensor, optional MPU9250/MPU6050 motion sensor, DVP camera expansion connector (OV2640/OV5640), TF card slot, and 2 × STEMMA QT/QWIIC. V1.1 uses a constant-current backlight driver for improved display stability.

FAQ

• Q. Why does my board keep failing to upload? A. Hold BOOT, press RST once, release RST while still holding BOOT, then start the upload.

• Q. How do I distinguish V1.0 from V1.1? A. Look for "V1.1" printed near the USB-C port. V1.1 uses a constant-current backlight driver — use the corresponding example.

• Q. When no battery is connected, the device reboots repeatedly? A. Without a battery, disable charging: PMU.disableCharge(). See the PMU_Example for reference.

• Q. The screen stays black or backlight is abnormal? A. Check that backlight configuration matches your board version (V1.0: PWM, V1.1: constant-current).
