An industrial-grade, highly integrated small-size display solution designed for HMI (Human-Machine Interface) upgrades. It is ideal for industrial control, IoT terminals, and compact smart equipment, balancing robust stability with flexible customization.

✅ Dual Versions Available

Touch Version (ASTG024W023-L240X320R-COF): Integrated 4-wire resistive touch screen, ready to use out of the box.

Non-Touch Version (ASTG024W023-L240X320N-COF): Supports external capacitive touch screens for customized interaction needs.

✅ Robust Hardware, Compact Power

Display: 2.4" TFT LCD, 240×320 resolution, 65K colors, 250 cd/m² brightness, 20,000 hours LED backlight life.

Performance: 200MHz ARM Cortex-M4F core, built-in 2MB PSRAM + 10MB SPI NOR Flash for smooth operation.

Durability: 3.3V low-voltage power supply, max power consumption <1W. Wide operating temperature (-20℃~70℃), humidity tolerance (10~90% RH non-condensing), anti-vibration, and natural air cooling for harsh industrial environments.

✅ Rich Interfaces & High Expandability

Communication: Default support for 1× UART2 and 1× CAN1 interface; reserved UART1/3/4 and CAN2 interfaces. Compatible with Modbus, Siemens, Mitsubishi, Delta, and other mainstream industrial protocols.

Peripherals: Integrated RTC and buzzer control. Reserved SD card, I2C, ADC, and SWD debugging interfaces. FPC 0.5mm-50P connector for easy integration.

I/O Resources: Abundant GPIOs supporting macro command logic for flexible control applications.

✅ Low-Code Development & Fast Deployment

HMILite Configuration Software: No UI coding required. Drag-and-drop controls (buttons, numeric displays, trend charts, alarms, QR codes, etc.) with offline/online simulation support. UI projects can be completed in as little as one day.

Advanced Features: Custom boot logos, multi-language support, project encryption, user privilege management, PLC linkage, and data acquisition capabilities.

✅ Rigorously Tested Reliability

ESD Protection: Contact discharge ±2KV / Air discharge ±4KV without malfunction.

EFT (Group Pulse): Passes ±4KV testing with no restart or display anomalies.

High/Low Temp Aging: Stable operation across alternating cycles from -20℃ to 60℃.

FAQ

01.How many communication interfaces does it have?

By default: 1× UART2 (communication serial port) + 1× CAN1.
Reserved: UART1 (print port), UART3, UART4, and CAN2.

02.Can I expand storage or connect peripherals?

Yes. It supports SD cards via reserved SD IO, and reserves ADC, I2C, and SWD debugging interfaces for peripheral expansion.

03.Do I need to write code for the UI?

No. We provide HMILite configuration software. You can design UIs via drag-and-drop controls, without C coding. It supports offline simulation before downloading.

04.Which PLC protocols are supported?

It supports Modbus RTU, Mitsubishi, Siemens, Delta, Xinjie, Omron, Panasonic, and custom protocols.

05.Is it suitable for industrial environments?

Yes. It passes ESD (±4KV air discharge), EFT (±4KV group pulse), and high-low temperature aging tests (-20℃~60℃). It works stably in 10%~90% RH non-condensing environments.

06.How do I download the program?

Connect the screen to a PC via the USB interface (pins 34/35) and download directly using HMILite software.
