The T5-4.7-S3 Epaper PRO is a highly integrated, ultra-low-power development board designed for IoT applications requiring long-range communication and dynamic visual display. Combining a 4.7-inch E-Paper screen (960×540, 16 grayscale), an ESP32-S3-WROOM-1 MCU (16MB Flash + 8MB PSRAM), and an SX1262 LoRa transceiver (supporting 433/868/915 MHz), this board enables energy-efficient data transmission and visualization with support for Wi-Fi 2.4GHz/BLE 5, capacitive touch, RTC, TF storage, and optional GPS. Its advanced power management system (BQ25896/BQ27220) and magnetic wireless charging support ensure extended operation, making it ideal for smart signage, environmental monitoring, asset tracking, and other battery-powered IoT projects.
