1. Introduction
In fact, I wanted to make an interactive device before, which can monitor some website information, so that I can see and give feedback in time. I have been exposed to the ESP32 series...
[i=s] This post was last edited by me on 2021-4-8 17:32[/i]As shown in the figure below, the highlighted part is the 3.3V routing of STM32F103. First, AMS1117-3.3 outputs 3.3V in the upper left corner...
I am currently working on a product for use in cars. All other circuits have been designed, but I am not sure how to handle the EMC of the power supply (the 12V power supply is taken from the car). I ...
