Re: Powering Arduino
We have used this module from Sparkfun for 12V->5V for our Arduino and LEDs..
https://www.sparkfun.com/products/9370 You need to calculate the value of an external resistor for your output voltage (check the datasheet), but it's easy to use and a high current rating. May need active cooling depending on the current you draw - it does get pretty warm with our LEDs. |

Re: Powering Arduino
There are three versions of the Analog Breakout. The 2009 version can supply 3 amps and uses a switching regulator. The 2010-2013 version uses a linear regulator and can supply 0.25 amps continuously. The 2014 version also uses a linear regulator and can supply 0.25 amps continuously (and doesn't require the battery voltage jumper to comply with R70).

Thanks for the link, I think we will give these a try. Randy |

This one on amazon says it can output 2A @ 12V with no heatsink. Could wire directly into the PDB connections off a breaker. These things all come out of china, so if you can deal with waiting a few weeks for shipping, you can check ebay for better prices and a wider array of parts/suppliers to choose from. |

Re: Powering Arduino
Randy,
The power supplies on the PD are designed with brownout in mind. They continue to put out down to at least 5 volts but typical is 4.5 volts. The cRio is only available in a 24 volt version as this is a standard industrial power supply. It actually has a wide voltage rating, 19-28 v as I remember. |

Re: Powering Arduino
Hi,
Does anyone know if we can use a second KoP 12V/5V DC-DC converter off a normal port on the pdb to power the arduino? Are there any rules against using a second one of the KoP DC-DC converters? Thanks |

Re: Powering Arduino
There are no rules to prevent this use.

Re: Powering Arduino
When we used Raspberry Pi's last year we bought a second power supply that is used for the wireless router. It gives a solid 5v under extreme conditions, hence the reason it is required for the radio. Of course you would need to power it off of the PD through a 20A breaker since it is a custom circuit. It worked great for us, but did raise some questions since there were 2 and 1 of them was plugged in to a 20A breaker. Just know the rules and be able to explain why you did it the way you did it and the inspectors will pass it.
