Edison power supply, minimal current ?

Hello,

I use the INTEL EDISON in my application, and in its datasheet, we can supply it between 3.15 and 4.5V.

I would like to use a 3.3V (because it is possible..), but when I make it, sometimes the Edison starts and sometimes not, or switch off later.

I think, it's because there is an electrical voltage drop (3.3V -> 3.10 / 3.15V)

But my power supply is reliable, it's a vigortronix 5W 3.3V.

What yo recommend me? It is really possible to use a 3.3V power supply for the Edison in 3.3V, and with which power?

Or no, and i must use an adjustable regulator, but with which power for my power block before?

Or other things.

Thanks,

François

If you are using intel edison arduino breakout board, then

You can power Intel Edison either using microUSB(5V) or using external adapter(7V-15V). If I am not wrong, 3.15V-4.5V is what edison module can supply to the digital/Analog outputs.

Hello François,

 

 

Thank you for interest in the Intel® Edison Breakout Board.

 

 

I think you may be right about the voltage drop that you experience when connecting your power supply.

 

 

I would recommend using a 3.3 V voltage regulator in order to achieve the stable DC voltage the compute module needs. The power supply that enters the voltage regulator depends on the chip that you choose.

 

 

I hope you find the previous information useful.

 

 

Regards,
