LILYGO T5 E-Paper S3 Pro with a capacitive touch interface

Shenzhen Xinguan Electronic Technology, commonly known as LILYGO, is a company dedicated to the development of IoT products. They have developed a compact microcontroller board featuring advanced e-paper display technology. The T5 E-Paper S3 Pro is equipped with a 4.7-inch ultra-low-power e-paper display, which is a key characteristic that enhances the board’s aesthetic appeal. This board also incorporates a capacitive touch interface powered by the ED047TC1 IC, capable of displaying 16 levels of grayscale.

At the heart of the LILYGO T5 E-Paper S3 Pro is the Espressif ESP32-S3-WROOM-1 microcontroller, known for its robust wireless connectivity options, including Wi-Fi 802.11b/g/n and Bluetooth LE, all supported by a dual-core CPU. The microcontroller features a variety of peripherals and offers capabilities for neural network computing and signal processing tasks.

The system-on-chip utilizes an Xtensa dual-core 32-bit LX7 microprocessor, which operates at frequencies up to 240 MHz. This module is designed for a diverse array of applications, including low-power IoT sensor hubs, smart home solutions, and serving as a networking card for Wi-Fi and Bluetooth connectivity. Even though the T5 E-Paper S3 Pro comes with a Type-C port, the manufacturers have designed the development board to support a MagSafe charger.

LILYGO recommends utilizing the PlatformIO setup due to the availability of application examples developed specifically for it. To get started, users should first install Visual Studio Code (VS Code) and Python. After launching VS Code, they need to search for and install the PlatformIO plugin from the extensions marketplace. Once the project is opened, PlatformIO will automatically download all necessary third-party libraries and dependencies.

The T5 E-Paper S3 Pro is currently available for purchase on the official website; however, it is presently out of stock. LILYGO has set the price for this product at $76.58. As the development board is open source, the schematic and 3D files can be accessed via the GitHub repository.
