Introduction As a first thought, one might think that the 0 Ohm resistor is unnecessary; after all, why would someone use a resistor with no
To read a resistor on a PCB, first identify the marking method. Through-hole resistors usually use color bands. SMD resistors usually use numbers, letters, or
An HDI PCB is a high-density interconnect printed circuit board. It uses finer traces, smaller vias, and denser routing than a standard board. Most designs
Choose a microcontroller when a product needs simple control, low power, lower cost, and fast firmware development. Choose an FPGA when the design needs parallel
VCC and VDD usually mean the positive power rail. VSS usually means the lower power reference. In many simple CMOS circuits, VSS connects to GND.
