3.5 Inch UART TFT LCD Display Module 320x480 IPS - China Suppliers & Factory Direct Sale

The 3.5 Inch UART TFT LCD (Model: ATFLet035 V40) is a next-generation smart display designed to eliminate the complexities of traditional GUI programming. Featuring a crisp 320x480 resolution and an IPS full-viewing angle, this module operates via a "Plug-and-Play" serial command system. Unlike standard displays that require intensive MCU resources, this 3.5 Inch UART TFT LCD offloads all graphical rendering to its internal GUI engine. By using simple string commands—similar to a standard "print" function—developers can display complex characters, values, and high-definition images instantly.

• 1 Code-Free GUI Design: Compatible with the ATF_UITool software, allowing engineers to build interactive interfaces (buttons, progress bars, waveforms) without writing a single line of display driver code.
• 2 Virtual U-Disk Technology: Simplifies resource management. By connecting via USB, users can simply drag and drop JPG images, configuration files, and resource scripts directly into the module's internal storage.
• 3 Flexible Orientation: Supports both vertical (320x480) and horizontal (480x320) display modes, adjustable via a simple configuration file to fit any housing design.
• 4 Rich Control Library: Built-in support for QR codes, infrared remote control (NEC protocol), numerical inputs, and real-time waveforms.
• 5 Industrial Reliability: Built with 8KV ESD protection and a wide operating temperature of -20°C to 70°C, ensuring stability in household appliances and handheld instruments.

• ● The 3.5 Inch Form Factor: This is the most popular size for handheld devices, offering enough screen real estate for complex dashboards while remaining highly portable.
• ● UART Serial Simplicity: Because it communicates via UART (TTL), it is perfectly suited for low-pin-count microcontrollers like the Arduino Uno, ESP8266, and PIC series, saving valuable I/O pins for sensors and actuators.
• ● C-Language Scripting: For advanced users, the module allows for C-language scripts to be added to controls, providing a layer of dynamic functionality that goes beyond basic static interfaces.

1. 1 Resource Updates: Connect the module to your PC via the USB T-port. The module will appear as a Virtual U-Disk. Drag your .ers resource files and TFTcfg.txt directly into the folder.
2. 2 Power Requirements: Ensure a stable 3.3V supply voltage. While the interface is UART, using a common ground with your MCU is essential for reliable data transmission.
3. 3 Display Configuration: Use the TFTcfg.txt file to set your default baud rate, brightness, and screen rotation (0°, 90°, 180°, or 270°).
4. 4 Direct Print Mode: Use your MCU's serial port to send commands like CLR(0); to clear the screen or SBC(15); to change background colors instantly.

• ✓ Application Matching: Choose this 3.5 Inch UART TFT LCD for projects requiring rapid time-to-market. If your project has limited flash memory on the main MCU, this smart display is a mandatory investment.
• ✓ Touch vs. Non-Touch: This model is optimized for high clarity; if your application requires user input without a touchscreen, utilize the built-in Infrared Remote Interface for navigation.
• ✓ Customization: HOTHMI offers factory-direct customization for FPC length, backlight brightness, and custom boot-up logos to align with your brand identity.
