Description
WCH CH32V307 RISC-V development board features 8 UART ports controlled over Ethernet
The CH32V307 is an interconnected microcontroller, based on 32-bit RISC-V core, with hardware stack area and fast interrupt entry. Compared with standard RISC-V, the interrupt response speed is greatly improved. With single-precision float point instruction sets added and stack area extended, the CH32V307 has higher performance, the number of U(S)ART is extended to 8, and the number of motor timer is extended to 4.
The CH32V307 provides USB2.0 high-speed interface (480 Mbps) and has built-in PHY transceiver. Ethernet MAC is upgraded to GbE and integrates 10M PHY module.
