Dilisi S 116.1 24 == 1.1  What is the LTS5 LoRa HMI Touch Screen? ==
Edwin Chen 2.1 25
Xiaoling 56.1 26
Dilisi S 116.1 27 The LTS5 is a (% style="color:blue" %)**LoRa / LoRaWAN HMI Touch Screen**(%%) designed for displaying information in IoT projects. It features a **5.0-inch HMI touch screen** and supports **Wi-Fi**, **Bluetooth**, and **LoRa** wireless protocols.
Edwin Chen 2.1 28
Dilisi S 116.1 29 The LTS5 is an open-source software project powered by an **ESP32 MCU** and a **Dragino LA66 LoRa** module. The extensive development resources available for ESP32 can significantly reduce development time.
Edwin Chen 2.1 30
Dilisi S 116.1 31 The LTS5's HMI touch screen supports **drag-and-drop** design, allowing developers to use SquareLine to easily customize the display UI for various applications.
Edwin Chen 2.1 32
Dilisi S 116.1 33 The LA66 LoRa module can be programmed to support either private LoRa protocols or the LoRaWAN protocol.

BoYang Xie 26.2 206
Dilisi S 122.1 207 The area for modifying widgets is called the **Inspector** tab. The Inspector tab consists of four sections: **COMPONENT**, **<WIDGET>**, **STYLE SETTINGS**, and **EVENTS**, as shown in Image 6.
BoYang Xie 26.2 208
Dilisi S 122.1 209 The second section allows you to adjust a widget's layout, size, position, alignment, flags, states, and more. When you select a widget on the screen, the name of this section changes to match the name of the selected widget.

252
BoYang Xie 51.2 253 To use the image widget, you should first add an image to your project. The image format must be PNG, and its resolution should not exceed 800x480 pixels. There are two ways to add an image file. One way is to move your image into the folder "…/squareline project/assets/", as shown in image 10. The other way is to click the "ADD FILE INTO ASSETS" button, then select an image from your computer to import. After adding, you can see the image in the "assets" area in SquareLine Studio, as demonstrated in image 11.

Dilisi S 123.1 264 ==== 5. The relationship between widgets ====
BoYang Xie 51.2 265
Dilisi S 123.1 266 Widgets commonly have two types of relationships: **parallel** and **parent-child**.
267
268 * In a **parallel relationship**, widgets' positions are determined relative to a shared reference object.
269 * In a **parent-child relationship**, any part of the child object outside the parent's boundaries is hidden by default. To make the child object fully visible, you must adjust its position to fit within the parent's range, as shown in Image 13.
