Introduction 1.Introduction 1.1. T-Display-S3 Pro T-Display-S3 Pro 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 2.33 inch IPS LCD. At the core of this module is the ESP32S3R8 chip. ESP32-S3 integrates Wi-Fi (2.4 GHz band) and Bluetooth 5.0 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 2.402 GHz to 2.480 GHz. The T-Display-S3 Pro manufacturer is Shenzhen Xin Yuan Electronic Technology Co., Ltd. 1.2. 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. 1.3. 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 …

This also means that no ground cutout area is required under the antenna. If there are several layers in the PCB, there is an advantage to add via holes for interconnection of the ground areas. It is also very important that there is a ground clearance around the NC pads and the RF feed pad, through all layers of the PCB. Otherwise, there will be capacitive coupling which may detune the antenna. Pin configuration PCB Layout (from evaluation board) The antenna is preferably positioned along one side of the PCB ground plane, where pin 1 shall be as close as possible to the layout corner. It is also recommended to implement a pi-matching network as seen in the PCB layout to compensate for eventual mismatch due to the practical implementation. The components can be positioned below the antenna next to the feed pad. See “Evaluation Board Outline & Matching Circuit” section for more details.

It has an arbitrary size of 100 x 50 mm and includes an SMA connector. The purpose is to give a reference design for an optimal antenna implementation. The evaluation board can also be used to test other implementations by cutting and soldering the PCB into any device. Evaluation board outline The evaluation board has a matching circuit implemented next to the antenna. This is aimed to enable optimization possibilities for the user. The component positions are sized for 0402 (1005 metric) SMD components. Matching circuit The antenna needs a matching circuit to adjust the resonant frequency balance. When delivered, the evaluation board is tuned for optimum balance at the 2.4 GHz band. The component values for this setup is C1 = 1.5nH, C2 = 0.5pF, C3 = N/A. However, it is common that the resonant frequency will shift during implementation in an arbitrary device. Therefore, this matching may be changed for compensation of such effects.
