If you're looking for a rugged, easy-to-use industrial human-machine interface (HMI) display, this ASTG035W023-B-L320X480R series serial screen is worth your attention. We've compiled key information from an end-user perspective to help you quickly assess its fit for your project:

Display performance: 3.5-inch TFT LCD, 320×480 resolution, 65,536 colors, 250 cd/m² brightness, LED backlight with 20,000-hour lifespan-fully meets visibility standards for industrial scenarios.

Touch experience: 4-wire resistive touch panel with 4H surface hardness, operable with gloves, ideal for factories, outdoor sites, and other harsh environments.

Hardware specs: 200MHz ARM Cortex-M4F core, built-in 2MB PSRAM + total 10MB onboard SPI NOR Flash, supports up to 50 screens with up to 50 controls per screen-handles routine equipment monitoring and data visualization with ease.

Reliability built in: Passed IEC 61000-4-2 ESD testing (±4kV contact discharge, ±8kV air discharge with no abnormalities); wide operating temperature range of -10°C~50°C; 10%~90% non-condensing humidity tolerance; seismic resistance rated at 10–25Hz (2g/30min across X/Y/Z axes)-reliable for demanding industrial sites.

🛠️ Easy Installation & Wiring

Wiring Made Simple: Clear Terminal Definitions

All models use a 5-pin PH2.0mm terminal block-just match the pins below:

TTL Version (0T0C-T): Pin1/4 = GND; Pin5 = DC 5V; Pin2 = RXD (3.3V TTL level); Pin3 = TXD

RS485 Version (1D0C-T): Pin1/4 = GND; Pin5 = DC 5~30V; Pin2 = RS485 B (-); Pin3 = RS485 A (+)

RS232 Version (1E0C-T): Pin1/4 = GND; Pin5 = DC 5~30V; Pin2 = RS232 RX; Pin3 = RS232 TX

Note: Power and communication share the same terminal block. Double-check voltage before wiring to avoid damaging the device.

Pre-cut the Correct Opening Size

Overall unit size: 115×71×25mm. Recommended panel cutout: 109×67mm. Snap-in mounting with housing-no extra protective enclosure needed.

💻 Zero-Coding Development, No Low-Level Driver Hassle

Comes with HMILite PC configuration software-drag-and-drop controls to build interfaces, no need to write low-level drivers:

Full Library of Ready-to-Use Controls

Includes toggle buttons, numeric input/display, animated pipeline flow, static graphics, image/GIF display, gauges, alarm prompts, dynamic trend curves, QR code generation, and more-covers most common interaction needs. Supports up to 50 macro instructions for custom complex logic.

Pre-Integrated Protocols-No Need to Write Your Own

Supports Modbus RTU, Mitsubishi, Siemens, Delta, Xinjie, Omron, and other mainstream PLC protocols, plus custom protocol options for integration with MCUs, inverters, servo controllers, etc.

Simulation Features Save Time

Run offline simulation to preview interface effects without flashing the screen. Online simulation lets you debug communication with connected devices directly from your PC-cuts trial-and-error time dramatically.

Practical Extra Features

Customizable boot-up logo for brand consistency

8-level user permission management to prevent accidental operation

3-second auto-save on power loss-no parameter loss during outages

Panel protection feature: auto-redirects to a preset screen after a user-defined period, ideal for leased equipment management

⚠️ Important Notes Before Use

TF cards must be formatted as FAT32 with a maximum capacity of 32GB-otherwise they will not be recognized.
Backlight brightness is not adjustable-confirm if this meets your requirements before deployment.
No USB port or USB drive support-all program updates must be done via TF card.
Do not exceed 30V for wide-voltage models (1D0C/1E0C), and only connect the TTL version to 5V power-incorrect voltage will damage the board.
Maximum 100 QR codes per project, 5 per screen-keep these limits in mind when designing interfaces.
