README
README.mdSTM32F302C8T6最小系统
这个硬件项目是用于取代原先F103C8T6开发板而制作的，也为其他硬件项目提供参考。相比于同等密度的F103，STM32F302拥有一个高速（5MSPS）ADC，并且额外增加了一个运放和三个比较器，适合模数混合的应用。另外由于其定时器带有输入时钟倍频的功能，其输出分辨率比F103更高。
板载功能除了必须的调试口，复位电路以及晶振电路之外，还引出了USB接口与两枚测试用的LED，另外还增加了一颗IMU（QMI8658C）的位置，用于实践测试IMU解算算法以及评估IMU性能。
最小系统板还配备了一块带有三个半桥驱动的底板（原来的目的是用于驱动电机，后面发现不符合要求），适合用于作为功率级使用。三个半桥均带有电流检测的功能。由核心板的5V经过升压达到11V输入驱动IC，而电流检测放大器的供电则由5V经线性稳压供电。
硬件说明
-
最小系统板内主控的模拟电源与数字电源可分开供电，可以选择使用额外的LDO LP5907为模拟电源供电，或者拖锡连接JP1直接连接模数电源
-
AMS1117输入输出的二极管D3必须焊接，否则会出现在调试时只接入3.3V而1117发热严重的情况
-
IMU的中断管脚INT1与栅极驱动底板的驱动输入引脚有冲突，按照目前的设计二选其一使用
软件说明
f302_minimal_test 内为早期测试核心板的代码，基本没有实际用途
imu_f302 内为IMU测试解算代码，读取QMI8658C解算角度，并将其通过USB虚拟串口发送至匿名地面站上位机。EKF解算算法详见这篇博客，新增加的ESKF解算算法见这篇博客

Questions
How big is the Power drive PCB?
It measures 58.8 × 60.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Power drive use?
121 parts, built around the IR2101PBF, MT3540, LP5907MFX-3.3 and BAT46. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Power drive KiCad files?
From the SourceLizi/F302-minimal repository on GitHub, at the commit this page was made from: the board is Hardware/Power_Drive/power_drive.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Power drive design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
