I want to do my first 6 (or more) layer board. If my circuit has a 5v bus and a 3.3v bus, is it normal to have these voltages on separate layers? If so, what is the best way to implement this? ( I am ...
I want to power a constant current LED (145mA & 200mA) at 19-21V.Since this will be powered by Li-ion battery connected to a tp4056, which is the most efficient way to boost the voltage from 3.7V ...
can somebody advise (or if you are so very much kind provide) a pcb with the functions of a 8 by 8 macro keypad and 2 rotary encoders support and using the pro micro to be the brains of the macro keyp...
Hi, I've been designing a keyboard pcb, and I'm a bit confused about GND and no net zones, as in when I should use them( both layers, or just one? Also, should I have isolated copper fills at ...
I need part number of material or its datasheet that I can use as a stiffener for FPC. Parameters of stiffiner are: Pl's thickness - 100um, adhesive's thickness - 50 um. Thank you
If "LIGHT AND MOTION SENSITIVE LAMP" circuit run by 220VAC then will it automatically power the sensor and relay or separate DC power needs to apply?Why there are two relays in above c...
