Intel Edison power question

Jump to solution

I'm using Eagle to design a PCB for myself to use for rapid prototyping with the Edison.

On the board I have a 12v power supply through a barrel jack or screw terminals, that's stepped down to 5v and 3.3v, the 5v is for powering some ICs, and the 3.3v is for powering the Edison.

I went to draw the net to connect the Edison to the power, and then realized that I didn't know where to input the power on the Edison, so I looked at the SparkFun schematic for the battery/power block: https://cdn.sparkfun.com/datasheets/Dev/Edison/SFE_Battery_Block.pdf https://cdn.sparkfun.com/datasheets/Dev/Edison/SFE_Battery_Block.pdf

Now I'm confused because the schematic shows power going to "VSYS/2.??", but on the edison pinout diagram, there is only "VSYS/1.??", no "2.??"

What pin on the Edison should I be applying my 3.3v power source to?

Hello Keith.M,

I recommend you to use the schematics of the Mini-Breakout Board and the Arduino Expansion Board as reference:

The Edison's power input corresponds to the VSYS pins (pins 2, 4, and 6). You can check in the schematics above where the VSYS pins are connected to.

Additionally, I recommend you to read the http://www.intel.com/support/edison/sb/CS-035274.htm Intel® Edison Boards — Compute Module Hardware Guide. You will find details about the Edison module and how to power it properly.

Regards,

Diego.

Thanks Diego!

I didn't know that the schematics for the breakout boards where avaliable, thanks for linking to those and the hardware guide! I'm surprised I haven't seen the guide before when researching Edison stuff, that's going to be a big help
