Much obliged for the appropriate response, my transfers have that choice yet since I have Lee's that ought to show the power express its no equitable on the hand-off side.

Re: Beginner PCB design for LED clock

I investigated your PCB explicitly to perceive what you did with the decoupling capacitors. A simple to recall general guideline while setting down decoupling capacitors is to dependably put them as close as conceivable to the stick they feed capacity to. At that point when laying the power follow, ...

Re: Do we need to control impedance of CAN BUS ?

For high-speed/FD CAN, both ends of the pair of signal wires (CAN_H and CAN_L) must be terminated. This is because communication flows both ways on the CAN bus. CAN_L is pin 2 and CAN_H is pin 7 on the standard 9-pin D-SUB connector. The termination resistors on a cable should match the nominal impe...
