There are many technical solutions for IoT device communication solutions and LTE technology used in IoT applications. Various industries and technical standard organizations are formulating correspon
I developed a development board with 430 to control a brushless DC motor with a Hall sensor. However, when everything is connected and the program is burned in, the Hall sensor always reports an error
How to answer such a question?[align=left][color=rgb(51, 51, 51)][font=宋体][size=4]Doesn’t a diode not allow current to flow in the reverse direction? Why in this picture, when the second and third dio
The power input is 18V, and the output needs to be 5V/5A, 12V/3A, -12V/2A. There are three output voltages. I don't know which company can do a better job of DC step-down.I found a L7912 power IC, but
Our company makes testing machines. Now there is a problem, if the sensor is not connected properly or the wire is loose.When doing the experiment, no force was detected, the motor kept turning, and i
