Easy DIY LED Tester (PCB + Schematic)

Here I talk about my last project: a simple LED tester. A fast way to test your LEDs, the circuit is full-THT, that means no SMD components at all. You can test LEDs from 0.1mA of current up to almost 50mA. The circuit will also show you the voltage drop of the LED, so that it is easier to calculate the resistor you need for your project Want beautiful PCBs? https://pcbway.com/g/zr03zR Want to support me?
