LILYGO T4-S3-241 Smart Display Electronics User Manual
Introduction
T-Display-S3
T-Display-S3 is a development board. It can work independently.
It consists of ESP32-S3 MCU supporting Wi-Fi + BLE communication protocol and
motherboard PCB. The screen is 1.9 inch IPS LCD ST7789V.
At the core of this module is the ESP32S3R8 chip.
ESP32-S3 integrates Wi-Fi (2.4 GHz band) and Bluetooth 5.0(LE) solutions on a
single chip, along with dual high performance cores and many other versatile
peripherals. Powered
by 40 nm technology, ESP32-S3 provides a robust, highly integrated platform to
meet the continuous demands for efficient power usage, compact design,
security, high performance, and reliability.
Xinyuan provides the basic hardware and software resources that empowers
application developers to build their ideas around the ESP32-S3 series
hardware. The software development framework provided by Xinyuan is intended
for rapidly developing Internet-of-Things (IoT) applications, with Wi-Fi,
Bluetooth, flexible power management and other advanced system features.
The RF frequency range is 2.412 GHz to 2.4 GHz. (WIFI)72 BLE: 2402-2480MHz
The T-Display-S3 manufacturer is Shenzhen Xin Yuan Electronic Technology Co.,
Ltd.
Arduino
A set of cross-platform applications written in Java. The Arduino Software IDE is derived from the Processing programming language and the integrated development environment of the Wiring program. Users can develop applications in Windows/Linux/MacOS based on Arduino. It is recommended to use Windows 10. Windows OS has been used as an example in this document for illustration purposes.
Preparation
To develop applications for ESP32-S3 you need:
- PC loaded with either Windows, Linux or Mac operating system
- Toolchain to build the Application for ESP32-S3
- Arduino that essentially contains API for ESP32-S3 and scripts to operate the Toolchain
- The ESP32-S3 board itself and a USB cable to connect it to the PC
-

FCC Caution
Any Changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.
This device complies with part 15 of the FCC Rules. Operation is subject to
the following two conditions: (1) This device may not cause harmful
interference, and (2) this device
must accept any interference received, including interference that may cause
undesired operation.
This transmitter must not be co-located or operating in conjunction with any
other antenna or transmitter.
IMPORTANT NOTE:
Note: This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more
of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
-
- Cnsult the dealer or an experienced radio/TV technician for help.
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment .This equipment should be installed and operated with
