Loading... **沁恒CH32V307VCT6[最小系统](https://blog.zeruns.tech/tag/最小系统)板，引出了所有IO口，一个Type-C连接到USB2.0全速OTG接口，一个Flash芯片 型号W25Q64 容量64Mbit 连接到SPI2接口，板上还有TL432电压基准1.25V(实测1.246V左右)可通过跳线连接到PC3的AD13，还有3.29V基准通过0欧电阻可连接到ADC参考电压VREF。** - 画了个 MSP430F149的最小系统板 开源出来了：[https://blog.zeruns.tech/archives/713.html](https://blog.zeruns.tech/archives/713.html) - STM32F030C8T6最小系统板和流水灯（原理图和PCB）：[https://blog.zeruns.tech/archives/715.html](https://blog.zeruns.tech/archives/715.html) ## CH32V307VCT6简介 CH32V 系列是基于青稞 32 位 RISC-V 设计的工业级通用微控制器。全系产品加入硬件堆栈区、快速中断入口等设计，相比标准大大提高了中断响应速度。CH32V303_305_307 系列搭载 V4F 内核，支持单精度浮点指令集，具有更高的运算性能。在产品功能上支持 144MHz 主频零等待运行，并根据不同应用方向提供了具有特色的资源结构，例如 8 组 USART/UART 串口，4 组电机定时器，内置 PHY 收发器的USB2.0 高速接口（480Mbps），千兆以太网 MAC 等。 沁恒官网产品简介：[https://url.zeruns.tech/Hcd8p](https://url.zeruns.tech/Hcd8p) 样品免费申请地址（运费到付）：[https://url.zeruns.tech/x67TF](https://url.zeruns.tech/x67TF) 芯片数据手册下载地址：[https://url.zeruns.tech/hDzqw](https://url.zeruns.tech/hDzqw) 提取码：cn7c ## 实物图      ## 原理图 图中的Type-C接口有点问题，CC1和CC2要用5.1K电阻**分别**下拉，我并联下拉了会导致使用Emark线时不能正常供电，立创开源平台上的项目已修正。  ## PCB **顶层：** TL432的1.25V（实测1.246V左右）电压基准可通过H8插跳线帽接到GPIOPC3的ADC13接口。 SW3是控制BOOT0和1自举引脚的，可以设置自举模式（具体看芯片手册2.5.2的 片上存储器及自举模式），都打到低电平（关闭）就行。 H9排针时用于接WCH-Link烧录代码用的。 H5排针是用于选择VBAT引脚的电源，如果没插电池就通过跳线帽接到3.3V电源，如果插了电池可接到BAT。  **底层：**  **如果不需要外接VDDA电源和VREF要将底面的R11和R7接上0欧电阻，然后VREF+可以通过R8和R9选择接LDO降压出来的3.3V电源或者TL432输出的3.29V参考电压，正常接R9即可 另一个空着。** ## 元件购买地址 -
