I just finished a product design. In the design, the measured data needs to be uploaded to the PC via USB. I used the simplest method: "Serial Port convert to USB" and one IC can do it. The product ha...
Can anyone help me calculate the resistor values of this circuit diagram? http://s3.photo.qq.com/567172606/94699521 (Sorry, I don't know how to post pictures.) The transistor is 9014, the thyristor is...
Power supply is often the most easily overlooked link in the circuit design process. In fact, as an excellent design, power supply design should be very important, which greatly affects the performanc...
Has anyone used Bosch's PM sensor?
It's Bosch's carbon smoke sensor. There is no communication protocol when I bought it. I'm begging (helpless) for the communication protocol......
1. In terms of local service, TI is actually a local company. From samples, services, ordering, speed and good service, I am afraid it is faster than many domestic chip manufacturers and suppliers. Th...
When you touch the surface of the power module, it feels hot. Is the module broken? Wait a minute, it is a little hot just because it is working hard. But high temperature has a great impact on the re...
