Today I tried GD's DMA+UART and encountered such a problem. On the one hand, it can be said that it was caused by my carelessness. On the other hand, I also hope that GD can unify some macro names of ...
[i=s] This post was last edited by Cheng Qiuxiang on 2019-1-22 10:40 [/i] What voltage regulator chips can output 6.4-6.5v? Input voltage 9v-12v, output current 2a, excluding voltage regulator diodes....
Today, when I was drawing PCB with AD17, I changed a component package. Unfortunately, the "spacebar" was invalid. However, nothing can be used on the schematic diagram. It doesn't work on the PCB. Mo...
The first discussion post is shown in Figure 1. A PMOS tube-involved overvoltage protection circuit uses a voltage regulator tube VT1 to stabilize the voltage at 5.1V. This way, the overvoltage protec...
