Hi, I have a question about the [OWire LEDs.
The [example schematic shows driving the LEDs from a 5V supply without a current limiting resistor.
However, in the “Features” tab of the [product page, it says “Forward Voltage: 3.2VDC”.
Also, in the [datasheet on page 9, it says “Please only use 14mA(Lamp LED) of forward current to drive LEDs whether one LED or multiple LEDs are being used.”
With a forward voltage of 3.2VDC, and a current rating of 14mA, that would suggest that I should use a 130Ω resistor when driving the LED from a 5V supply.
So, should I be using a current-limiting resistor as implied by the datasheet, or should I just drive it with the full 5V as shown in the example schematic?](https://cdn.sparkfun.com/assets/4/6/6/f/4/0-Wire_RGB_LED_Datasheet.pdf)](https://www.sparkfun.com/products/21209)](https://cdn.sparkfun.com/assets/7/9/e/1/3/OWire_Example.pdf)](https://www.sparkfun.com/products/21209)
