What a talent! The test result of the pegboard: in a normal office environment, the communication distance with the mobile phone is up to 30 meters.
The antenna is a solder wire of about 31mm, which i...
1. Input voltage is too high
The input parameter of the power module is abnormal - the input voltage is too high. This abnormality can cause the system to not work properly, or even burn the circuit. ...
The operating voltage of RS-485 transceiver is low (about 5V), and its withstand voltage is also very low (-7V~+12V). Once overvoltage is introduced, it will break down and be damaged. When there is s...
Compound voltage overcurrent protection, it is a voltage compound element composed of a negative sequence voltage relay and a low voltage relay connected to the phase voltage. As long as one of the tw...
This application report and the associated code provide a way to copy compiled program segments from the flash of the TMS320F28xxx to ram, which can increase the code execution speed. This solution im...
As the title says, the normal specification check in PCB is as shown below, but I clicked the document view in the lower left corner, and then the rule check became Figure 2. Can someone teach me how ...
