PCB Network City News When it comes to PCB boards, many friends think of how they are ubiquitous around us, from all kinds of household appliances, various components inside computers, to various digital products. Almost all electronic products will use PCB boards. So what exactly is a PCB board? A PCB board is a Printed … Read more
There are many sensitive components inside a microcontroller, and these components are very sensitive to external factors. If they are affected by electromagnetic interference, it can easily lead to the system not operating normally and stably. Therefore, electronic engineers must take reasonable measures to enhance the anti-interference performance of sensitive components. So how should this … Read more
The device consists of a handheld main unit and a battery pack. The handheld main unit features an integrated design with a tri-band transmitter antenna, capable of simultaneously generating 2.4GHz/5.8GHz frequency drone control interference signals and satellite positioning interference signals. By blocking the uplink control channel and satellite positioning channel of the drone, it causes … Read more
Enhancing anti-interference is one reason. Standard UART can choose 16x sampling or 64x sampling; I personally think it should be for convenient frequency division design. The RXD front end of the standard UART has a “1 to 0 transition detector.” When it continuously receives 8 ground level signals on RXD, the detector considers that the … Read more
