If the microcontroller serial port and the driver module are placed on the same wire and the load is working, it will burn the microcontroller. What is the best communication method for this serial po...
Several ways of current sampling1. Use sampling resistors directly and ADC to measure the voltage drop on the resistor without processing circuits such as op amps. 2. Use sampling resistors and ADC to...
Taking advantage of the 0-yuan proofing opportunity of Jiali Chuang, I made a few PCB rulers by myself, as shown in the picture. I will send them to you free of charge. If you like them, you can send ...
