GigaDevice has been busy pushing their RISC-V GD32V MCUs capable of surpassing Arm’s Cortex-M3 in both power and performance. While there are a pair of development boards and starter kits that use the GD32V, they’re not exactly easy to get a hold of unless you can read Chinese, as they are listed on Tmall’s website and Google Translate sorely lacks in this area. There is good news, though, as Shenzhen-based Sipeed has released a development board that uses the GD32V MCU and has it listed on Seeed for a mere $4.90.
