Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
I am debugging a NB module, which has an RS232 interface. I can debug it on the computer by using a USB to 232 cable. I also made a CH341T circuit and want to use 430 to send AT commands. The schemati...
Impedance actually refers to the parameters of resistance and reactance. Because the PCB circuit (bottom of the board) needs to consider the installation of electronic components, and the conductivity...
