Model WL0F00043000WGDACSA00 is a 4.3-inch RS485 Smart Display from WINSTAR, designed as a slave device controlled via RS485 commands using the Modbus protocol. It integrates WINSTAR’s wide temperature IPS TFT WF43WTWAEDNGA and a 4-layer FR4 PCBA with built-in firmware, delivering a reliable and streamlined HMI solution.
This Smart Display enables rapid project development while minimizing costs and engineering effort. It supports single-master (HOST) platforms such as PCs (via USB-to-RS485 dongle), MCUs, and Raspberry Pi.
WINSTAR GUI Builder is a Windows-based drag-and-drop tool featuring a WYSIWYG interface that allows you to create Smart Display GUIs without coding, significantly reducing development time. This tool is available for free trial by contacting us to request the software.
Our Smart Display products are built on STM32 MCUs from STMicroelectronics, enabling advanced customization using ST's official development tools. Development with these tools requires owning the WINSTAR Smart Display hardware.
If you have purchased a WINSTAR Smart Display and wish to develop using TouchGFX, please contact us to obtain the initial code.
We also offer demo sets with all necessary accessories to help you implement your GUI design on WINSTAR Smart Displays.
