This is really really cool. I want to get my hands on some capable riscV board.
What is the fuss about RISC-V? Why could I want a RISC-V board over an ARM board.
Because RISC V is ope hardware.
ARM is owned by a company. RISC-V instruction set is open.
The ARM company is also owned by Softbank which launders blood money from Saudi royalty/oligarchs: https://www.vanityfair.com/news/2018/10/i-wouldnt-take-that-money-saudi-arabias-dirty-investments-could-be-trouble-for-softbank
Other than being open source which others have already mentioned, the RISC-V instruction set is very optimized, having been developed with the full hindsight of every ISA that came before it as well as being designed for the capabilities of modern silicon, RISC-V cores have the potential to be a lot more efficient than any of the existing dominant ISAs.
Having an open ISA like RISC-V increases competition in the market. Better for us consumers.
