SunFounder ESP32 Starter Kit
Forward Voltage
The Forward Voltage is a very important parameter to know when using LEDs, as it determines how much power you
use and how large the current limiting resistor should be.
The Forward Voltage is the voltage that the LED needs to use when it lights up. For most red, yellow, orange and light
green LEDs, they generally use a voltage between 1.9V and 2.1V.
