Custom CH32V307VCT6 development board RISC-V core support RT-Thread onboard WCH-Link debugging Manufacturer

Overview:
 CH32V305/7 series is an interconnected microcontroller based on 32-bit RISC-V design, equipped with hardware stack area and fast interrupt entry, which greatly improves the interrupt response speed on the basis of standard RISC-V. Add single-precision floating-point instruction set, expand the stack area, and have higher computing performance. Expand the number of serial U(S)ART to 8 groups, and the motor timer to 4 groups. Provide USB2.0 high-speed interface (480Mbps) and built-in PHY transceiver, Ethernet MAC upgrade to Gigabit and integrated 10M-PHY module.
