About the Upper board

Upper board is an open source PCB design by Peize-Liu, published on GitHub. It is a 2-layer board measuring 50 × 50 mm, with 120 components from 29 distinct parts.

Other key parts include the CH340C, mcu_STM32H750VBT6, AP1117-33, W25Q128JVS and ICM-20602. By type, the board carries 61 resistors, 30 capacitors, 12 diodes, 8 ICs, 5 connectors and 2 crystals.

It belongs with the robotics & motion and sensors designs in this gallery.

2021 年 8月16日： 大家好，因为github 的dns 污染，国内网络经常出现无法上传和下拉提交的问题，所以现在整个工程都会在gitee：https://gitee.com/mortyliu/UESTC_404APD 上进行维护。同时也来说一下最近做的一些事情。

从做四轴飞行器开始，我的梦想就是到大疆联合实验室深造。所以从四月考完托福后，就开始着手看vSLAM 的内容，直到七月中旬，我算是把60-70%的数学坑填平了，来来回回李群和李代数 反复推演了六七遍，将ORB-SLAM1的论文看了四五遍，算是把大概结构理清楚了。 接着7月份我开始优化飞行控制器的硬件设计，以及重新学习了AHRS的相关内容，之前对于AHRS都是拿着别人的代码直接使用就完了，并没有深度去理解里面的数学原理（非线性优化，刚体运动学等）。这一次是将整个姿态解算的过程从论文到代码完全看了一遍，同时调通了所有的传感器，将算法适配到了404APD上。在这之后看了一些关于PID更深的研究，了解了一些模糊PID的内容和一些PID为基础的改进算法。个人认为可以在项目最后进行实现。…
