CH32V307V-EVT-R1 Evaluation Board 32-Bit MCU for RISC-V4F Processor 480Mbps PHY Development Board with WCH-Link Function

Description:
- CH32V307 is a high-capacity general-purpose micro-controller designed based on 32-bit RISC-V core, equipped with V4F core and supports single-precision floating-point instruction set for higher computing performance. It supports USB2.0 high-speed interface (480Mbps) with built-in PHY transceiver, Gigabit Ethernet MAC, etc.
- Application: Medical and health equipment, micro printers, card readers, security and monitoring alarms.
- The CH32V307V evaluation board comes with WCH-Link for online debugging and download. When using the SWD mode for program download and debugging, generally 4 wires are used, namely the power line VCC, ground wire GND, data line SWDIO, and clock line SWCLK. The SWD connection method is shown in the following figure. Short circuit the CLK and DIO, using the WCH-Link interface to download.

FAQ:
Q: How can I download through USB or serial port?
A: BOOT0 is connected to a high level, connected to a computer or P8 serial port through any U port on the board, and then connected to a computer through a USB transfer tool. The program is written through the computer's ISP tool. After programming, if you run the target program, you need to connect BOOT0 to the ground.
