Polos CH32VXX RISC-V Breakout Boards

CH32V Series MCUs are designed by Qinheng Microelectronics Co., Ltd., focuses on connectivity technology and microprocessor research and is an IC design company. CH32V Series MCUs are low-cost & powerful functions like BT, USB2.0/3.0, CAN, I2C, SPI, USB PD and so on. So we develop the Polos CH32Vxx RISC-V Breakout Boards. Qinheng Provide C/C++ SDK, Arduino Library, and MRS IDE. We perfer to use Embedded Rust, We will support Embedded Rust development in CH32Vxx RISC-V MCU.
