GD32 is a ARM Cortex Mx family produced by GigaDevice.
The GD32 family represents an excellent alternative to the STM32 family and in general also for other manufacturers of Cortex Mx.
For more info concerning Cortex Mx architecture see here and here.
Up to now the Cortex Mx families available are shown below but more will arrive as soon.
