WL0F00101000JGDAASA00 is a 10.1-inch Smart Display_RS485 series TFT, defined as a slave device controlled by a master device via RS485 command to render display content on the display screen and return touch event data with Modbus protocol data. WL0F00101000JGDAASA00 is featured with WINSTAR wide temperature TFT WF101JTYAHLNB0 and a 4-layers FR4 PCBA built-in firmware. This 10.1" RS485 series TFT is an easy-to-use product that allows you to develop projects rapidly in a cost-effective way. WINSTAR RS485 Smart Display support single-master (HOST) platforms, such as a computer (with USB2RS485 Dongle), MCU, and Raspberry Pi.

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).

We’ve also pushed the sample code on Github for your ST platform design reference: ► Link to Github

  • Design the UI without writing a line of code by WINSTAR GUI Builder! (Link to GUI Builder User Guide)
  • Designed with STM32F series MCU and Support STMicroelectronics' (ST) software development tools.


WINSTAR developed a Windows app. for Smart Display GUI design. WINSTAR GUI Builder software allows customers to simulate their GUI design in advance by using the drag-and-drop Widget preview function; customers can also create their ideal GUI. WINSTAR GUI Builder software supports Windows systems only; it can fulfill What You See Is What You Get (WYSIWYG). The new version of built-in software is a 3-in-1 APP; we combined three application templates for optional, including industrial, vehicle and medical applications. Please press the preferred application and hold for 3 seconds at the first time power on. Customers can change to another template by using GUI Builder to change the application.

Try before you buy! Contact us to download WINSTAR GUI Builder application.

We also provide demo set with all needed accessories for you to realize your GUI design on smart displays.
