I originally wanted to buy two copies, but due to the restrictions, I chose this book. It is a very good book and I like it very much. Since I cannot buy two copies, the administrator provided me with...
[align=left][color=rgb(51, 51, 51)]During the circuit design process, applications engineers often overlook the layout of the printed circuit board (PCB). The problem often encountered is that the cir...
The silk screen of the last PCB eeworld.com was dried up by the solder layer and the power interface was reversed. I re-drew it this time. The accelerometer sensor has 14-bit accuracy from Freescale. ...
