written in front
I believe that most people gradually understand the whole picture of the hardware from the case, and I am no exception; I still don't understand a lot, but I hope it can help other novices.
If the boss also has good information to share, you can also comment in the comment area and learn together~

1. PCB
Follow the video to draw a 32-board board . After drawing it in a daze, you probably have an understanding of the process.
Then the remaining knowledge is how to customize the schematic diagram and corresponding package of a module. (Find the chapters in other PCB videos by yourself)
But under normal circumstances, you can change the existing package and save it as your own package.
Compared with DIY and novices (one-stop service is required) for PCB making, Jiali Chuang is better.
How to draw the schematic diagram of hardware
-
See the application circuit in the hardware data sheet;
The data sheet is stinky and long, we don't need to worry about it too much, we just go straight to the application circuit, but some basic parameters still need to be understood.

Jiali Chuang’s open source square learns how other people draw this module. You can learn a lot from it, such as how to design MPU9250 and LDO, etc.
drive
Recommend the electronic devices of Weixue Electronics , its information is very complete! Very suitable for Xiaobai! Find a module such as the NRF52840 development board to play with, burn the code and you will know how the process goes!
at last
Keep improving yourself from the project information, and you will basically get started~
