WL0F0007000A8GDAASA00 is a 7-inch RS485 series smart display designed as a slave device that displays screens and reports touch status based on commands from a master device. This module consists of an IPS TFT display WF70A8TYAHLNGB paired with built-in firmware on a 4-layer FR4 PCB, integrating touch, display, and control functions.
This product is easy to use, significantly reducing development time and cost, accelerating project time-to-market. It supports multiple host platforms, including PCs (via USB to RS-485), MCUs, SBCs, and Raspberry Pi.
Features of the 7-inch RS485 smart display:
- +12V input (range: 5V–16V), power consumption approximately 6W.
- Power-on self-test with automatic screen activation.
- RS485 communication interface supporting Modbus protocol.
- Built-in 16MB flash memory for storing fonts and graphical objects.
- Supports capacitive touch panel and buzzer control.
- Compatible with multiple platforms, such as PC and MCU.
- Includes GUI Builder for interface design without programming. User guide
- Equipped with STM32F series MCU and supports ST development tools.
Winstar provides a Windows-based GUI Builder that allows drag-and-drop design and real-time preview, enabling fast WYSIWYG interface creation. The latest version integrates three application templates (Industrial / Automotive / Medical). Users can switch templates by pressing the option key for 3 seconds at startup, or change templates anytime via the GUI Builder.

Smart Display products are designed with STMicroelectronics' (ST) controller which supports ST development tools like TouchGFX and STM32CubeIDE. You can also use ST tools to design WINSTAR Smart Display modules besides GUI builder.
- TouchGFX: An advanced free-of-charge graphic software framework optimized for STM32 microcontrollers.
- STM32CubeIDE: An advanced C/C++ development platform with peripheral configuration, code generation, code compilation, and debug features for STM32 microcontrollers and microprocessors.
- STM32CubeMX: A graphical tool that allows a very easy configuration of STM32 microcontrollers, as well as the generation of the corresponding initialization C code for the Arm® Cortex®-M core or a partial Linux® Device Tree for Arm® Cortex®-A core, through a step-by-step process.
- STM32CubeProg: An all-in-one multi-OS software tool for programming STM32 products. It provides an easy-to-use and efficient environment for reading, writing and verifying device memory through both the debug interface (JTAG and SWD) and the bootloader interface (UART, USB DFU, I2C, SPI, and CAN).
