The "W806" microcontroller was developed by WinNermicro. It uses the kernel "Xuantie E804" from the company "THEAD Semiconductor" built on the "CSKY" architecture.
The debug board belongs to the company "HiLink", mainly it is engaged in the promotion of this controller.
The chip operates at a frequency of 240 MHz and has a high computing power.
The W801 microcontroller was also released, which is an addon W806. It added 1MB flash memory and Bluetooth and WiFi wireless modules.
At the moment, you can write and compile the firmware using the "CDK" development environment. Developer Plans to add W806 support to Arduino IDE.
