Introduction
The T5-4.7-S3 Epaper PRO is a versatile IoT device designed around the ESP32-S3-WROOM-1 main chip (8MB PSRAM + 16MB FLASH). It integrates a LoRa SX1262 long-range communication module, a 4.7-inch E Ink display (low-power, persistent display), and a capacitive touchscreen with two-point touch support.
The device supports expansion with an L76K GPS module (positioning data transmitted via TX/RX pins) and a real-time clock (RTC) module (time synchronization via SDA/SCL pins). It features convenient MagSafe magnetic charging, a built-in TF card slot, and M4 screw holes for mounting or external accessories.
With a variety of interfaces (SPI, UART, etc.), it is compatible with sensors and external devices, making it suitable for applications such as electronic labeling, remote monitoring, and outdoor navigation. It offers low power consumption, high compatibility, and flexible interaction.
