Introduction
The LILYGO T5-4.7-S3 Capacitive Touch Screen Development Board is an e-paper (E-Ink) solution based on the ESP32-S3-WROOM-1-N16R8 chip, which integrates 8MB of PSRAM and 16MB of Flash. This product features a 4.7-inch capacitive touch screen (supporting two-point touch), a PCF8563 real-time clock (RTC) chip, a USB Type-C interface, and a Li-Po battery connector (JST-PH 2.0mm), supporting battery voltage monitoring (Bat ADC).
It offers a 40-PIN GPIO expansion interface compatible with Raspberry Pi, includes an onboard TF card slot, and features dedicated screen control signals (STV/LE) and an SPI interface (CS/SCLK/MOSI/MISO). The board is designed with a 2.5D curved edge and is tailored for low-power e-paper applications with touch interaction, such as information displays, smart home terminals, and portable devices.
