Vin To Pin Keygenguru
Vin To Pin Keygenguru Average ratng: 4,2/5 2570votesThis maybe a very stupid question but, how much power is available via Vin pin? I am assuming it is 5 volts, but how much amps are provided? EDIT: I am trying to run a dc motor using ardumoto shield, AFAIK it gets power from vin, arduino is connected to a power source that provides 9v 2amps, so i am assuming say if i have x volts and y amps on the vin pin, i can get a motor according to this spec? Question someone said ardumoto supports up to 50v and 2 amps, i am trying to figure out how pass more current to the driver shield to run a dc motor in a RC car. According to the spec sheet, which I got from a link from the SparkFun Ardumoto site, the device can take 46V up to 2A per channel, 4A total, for close to 100W per channel or roughly 1/8 HP (.13).What is the Vin Pin for?

I always asumed it was a different option to power the board, but it seems to act more like a 5V supply. At 2A, 9V, you're looking at 18W or 1/40 hp, which might be too low.

I've added a comment to post the motors you have used on the other question, and if you would be so kind, post the power supply, code, and any other customizations you have made as well.
It sounds like you may need more power, but if you post this info we can certainly help you troubleshoot and make sure nothing else is going on. – Jan 22 '10 at 19:33. Vin pin is connected directly to the external power supply you use (if you are not powering from USB).Voltage is therefore down to the the supply itself. Amps available is also down to the supply (less a bit for the Arduino consumption). In general I would not advise drawing more than 1 amp through the board - if you need that sort of power then you should be connecting directly to power supply. If you are powering from USB then there is nothing on Vin.If you (say) use a power adapter giving 9V and 2A then you will get 9V and a little under 2A, say 1.9A at the Vin pin.

You should consider editing the question above to add this. I'm a bit confused as to what you mean.

Is the connector rated at 9V, 2A, or is your connector hooked up to a power supply that can yield 9V at 2A?If it's the former, no: Whatever you are using (say, a battery) will determine your specs, and if you go over the adapter's limits you risk causing permanent damage. If it's the latter, possibly, but remember the Arduino will need current to run as well.It sounds like you have a project in mind. Perhaps if you told us more about the project, we could give more helpful answers. – Jan 22 '10 at 17:54. The Vin pin is NOT 'DIRECTLY CONNECTED to the external power supply', or at least is NOT at the same voltage. This is obvious from direct experimentation with a wall wart with regulated (yes, regulated) voltage, this one at 1A capacity.
