In circuit design, there are various power symbols that often confuse people. Today, I have compiled 27 of them to share with everyone.The following V represents the meaning of Voltage.1. VCC: C can be understood as the Collector of a transistor or Circuit, referring to the positive terminal of the power supply.2. VDD: D can … Read more
The English terms on circuit boards, in addition to letters and numbers representing component numbers, also include some signal annotations such as VCC, VDD, GND, etc. We often see these English terms on circuit boards, but what do they mean? Let’s decode them together. Before that, let’s familiarize ourselves with the letters representing commonly used … Read more
The chassis is made of metal, and there is a screw hole in the middle, which connects to the ground. Here, a 1M ohm resistor is connected in parallel with a 0.1uF capacitor to the ground of the circuit board. What are the benefits of this setup? If the chassis ground is unstable or has … Read more
