Description

The WL0F00039000FGAAASA00 is a 3.9-inch Smart Display module from WINSTAR's CAN series. This slave device receives display commands and sends touch event data via the CAN bus protocol. It integrates a standard 3.9-inch bar-type TFT display (WF39FSWASDNG0) and a 4-layer PCBA with embedded firmware developed by WINSTAR.

Demo set host can be used on multiple platforms, including computer (with USB to CAN dongle), MCU, and Raspberry Pi (with PiCAN2).

CAN Bus Interface Advantages

  • High noise immunity for reliable data transmission in noisy environments
  • Efficient multi-node networking enabling seamless device communication
  • Supports flexible custom CAN ID protocol with fixed default baud rate of 250 kbps
  • Ideal for industrial control, automotive systems, and complex machine networks

Product Features

  • Input voltage range: 5V to 48V (typical 5V)
  • Integrated 3.9-inch bar-type TFT with 800 nits (typical) brightness
  • IPS panel with wide viewing angles (80° all directions)
  • Operating temperature: -30°C to +80°C
  • Capacitive touch panel (CTP) support
  • 16MB built-in flash memory for fonts and object dictionary
  • Self-testing function at startup
  • Embedded buzzer controlled by master device
  • GPIO pins for extended control
  • STM32F series MCU, compatible with STMicroelectronics software tools

GUI Development Support

The WINSTAR GUI Builder software (Windows) enables users to:

  • Design user interfaces with drag-and-drop components
  • Preview and simulate GUI layouts before deployment
  • Develop without coding
