This open-source development board is powered by the Renesas RA6M3 microcontroller (R7FA6M3AH3CFB), featuring the following specifications:

• RA6M3 (R7FA6M3AH3CFB) – Arm Cortex-M4F core (up to 120MHz); w/ 2MB Flash/640KB RAM, integrated TFT controller, 2D accelerator, and JPEG decoder

 

For connectivity, the board integrates the RW007 which is described as a SPI/UART Wi-Fi module based on the Cortex-M4 Wi-Fi SoC developed by Shanghai Ruiside Electronic Technology Co.  

The following RT-Thread-Studio GitHub contains some documentation and examples related to the board. The demo video above also shows some of the capabilities of the board. 

 

This RT-Thread article indicates that the HMI-board “comes pre-burned with the RT-Thread 5.0.0 release version and has the FinSH component enabled by default (connected to the DAP-Link virtual serial port) in addition to demo examples.”
