Technical overview

The on-board microcontroller is the STM32F405RGT6 from the STM32F405R family.
The board targets developers who want to add peripherals through its available standard interfaces.
A user manual and schematics are provided as technical documentation for the board.
Demo code is available for touch LCDs, including the 2.8-inch resistive touch LCD and GT911-based capacitive touch LCDs (7-inch and 4.3-inch).
Additional resources include IAP source code (USART and ETH), ST libraries, and a Keil device package.
Official datasheet documentation covers the STM32F405/407, F427/429, and F437/439 variants plus the reference manual.

Notes and version constraints

Board programming is only supported via a JTAG/SWD programmer; direct USB programming with STM32CubeProgrammer without an ST-Link is not supported according to the source.
If the 2.8-inch resistive touch LCD does not display after flashing, the source recommends using the latest sample program for that display.
For GT911 capacitive touch LCDs, use the matching routines based on display size (7-inch or 4.3-inch).
Technical support is available weekdays 9 AM – 6 PM GMT+8; tickets are typically handled within 1–2 working days.
Some resources (e.g., libraries and source code) are provided as archive files; their version compatibility should be verified before use.
