Based on the thriving RISC-V open-source instruction set architecture, WCH optimizes and expands for low-power and high-speed response applications. It is equipped with free development tools such as IDE, exempting third-party kernel technology from licensing and commission fees. Through built-in and combined professional interface peripherals such as USB, PD, low-power Bluetooth, Ethernet, etc., WCH has built an MCU product line that not only has a global future ecosystem but also can be independently controlled and highly competitive in the long term.
