Viewing BuildCircuit’s Gerber Files on EasyEDA Gerber Viewer

We have been using different online Gerber viewers for checking our Gerber files before sending the PCB designs for manufacturing. We have now started using EasyEDA’s Gerber viewer because it helps us to visualize the PCB that would appear after it is manufactured. The application is pretty straightforward and we can check different files to see the changes on…

What is a voltage divider circuit

A voltage divider network is a fundamental electronic circuit used to divide a voltage into smaller fractions. It consists of two or more resistors connected in series or in a string, which create intermediate voltage points between the supply voltage and ground. Voltage dividers are commonly used for various purposes in electronics, including setting reference…
