ecLeds is a board with 4 LEDs designed to use in a breadboard with the purpose of simplifying the prototyping task taking very little space given its reduced physical dimensions.
Its composed of two red and two yellow LEDs, each with an in series 1K resistor that will receive a voltage between 3.3 and 5 Vdc.
- Dimensions: 12 mm x 14.2 mm.
- Red LED power consumption: 3.2 mA @ 5Vdc, 1.5 mA @ 3.3Vdc.
- Yellow LED power consumption: 3.1 mA @ 5Vdc, 1.4 mA @ 3.3Vdc.
The PCB schematic is very simple, 4 LEDs with resitors in series.
In order to turn a LED on, the pin close to corresponding LED (labelled as +) shall be connected to either 5 or 3.3 Vdc, the corresponding pin next to the resistor will go to ground or 0 Vdc.
