Not to mention that it is RISCV. I have half a dozen RISCV board so I'm already familiar with the processor. I've even created on softcore RISCV on my FPGA. But I'm pretty sure I'm going to spend a lot of time trying to cross-compile software for this Grayskull Dev Kit.
I can buy a low-end NVIDIA GPU for about $200 and it will "just work".
