Smart car main control board + sensor circuit board

Overview

The designed smart car circuit board is a puzzle, including the car main control board, 370 motor Hall sensor circuit board, single motor driver board and an additional 358 operational amplifier, four circuit boards, four circuit diagrams and principles are drawn at the same time in a file. Among them, the Hall sensor needs to be used with a 26-pole magnetic ring. The main control of the car includes stm32 microcontroller, dual motor drive, infrared sensor, independent button, esp8266 and other modules. One shortcoming is that the power supply voltage cannot be too high, due to the 7805 voltage difference Excessive size will cause serious heating problems. It is recommended to use a motor below 9V. The power button switch needs to be confirmed to be of appropriate size.

No power in sim card holder
I used a sim300 module, but it couldn't connect to the line. Later I found that the pin that the module used to power the sim card holder had no power. What's the reason? Everything was working fine b

Aren't you working on power supply in the forum? Where are the people?
What's going on? No one is participating? It's so depressing.
