I recently ordered some arduinos from ebay, I didn't realize it had different specs than the original Arduinos.. My other projects. I apply 15v to VIN pin and it works fine.
After I purchased these, I apply 15v to the arduino and I thought it should handle it yet the voltage regulator started smoking. As I looked on the ebay page I noticed in the description it says it takes 5-12v of external power.. Are arduinos made differently(I bought it cheap but didn't know it had different components).
Here is the eBay link.
Can I add a resistor to the VIN pin and the power supply wire to reduce the voltage? Or how would you suggest being able to power this 12v Arduino with 14-20v? Also, I am just powering the Arduino along with the RGB pins on LEDS. The leds have 12v pin, R, G, B which I have the proper components for. If the length is about 6ft, will the solution be enough current?
