Its main chip is the STM32F334R8TX, from the STM32 family. Other key parts include the INA240A1PW, GS8332-SR, SIT1042/3, RY8411 and RS3236. By type, the board carries 67 resistors, 13 diodes, 12 capacitors, 11 ICs and 11 transistors.
From the project
C++,KICAD，H桥升降压，拟合，测电流电阻
11.1 现在的问题是电容端口短路，初步怀疑是原件选型错误，解决方法：加上了群里的同学一起讨论，和队里的研究生一起排查，看研究生的学习笔记，学习 C++
11.13 GAME WILL OVER，lucky，终于冲放电成功了，不报错，不过另一个的上板电流采样芯片可能坏了，等快递
11.18 第二个也做出来了，一开始错误的原因是底盘电流检测芯片选型错误，要 INA240PW1 才是对的，INA240PW2 的增益是不同的 这如此种种也不过如此啊
11.20 上车正常，最终效果：可以成功存储能量，要用的时候再输出，根据功率自动选择存储还是释放，功率闭环 + 缓冲能量闭环
