Razor 9 DOF IMU JST Connector?

Using Arduino Project Guidance
#1

Hello all!

Sorry if this is the wrong forum, I wasn’t sure which of the many forums to post in.

I’ve been looking at my Razor 9 DOF IMU and can’t seem to find the right type of JST connector to hook it up to my LiPo.

I was told by a friend that I would need to power it externally as the draw from my seeeduino mega is too great after hooking up my GPS module so i’m looking to try and find the right connector for the job.

So far, i’ve ordered three different types of JST connectors and non of them seem to fit at all. Can anyone identify the correct name of the connector on the Razor?

Here’s an image for reference: http://airhacks.org/wp-content/uploads/9DOF_razor.jpg

Looking around on the internet, all I can seem to find are the same connectors i’ve already ordered. Any help identifying this would be most appreciated.

As an aside: the razor tech sheet says:

“The 9DOF operates at 3.3VDC; any power supplied to the white JST connector will be regulated down to this operating voltage.”

Am I correct in assuming that if I feed the IMU straight from my 11.7v LiPo, it will regulate the voltage down to 3.3v or do I need to regulate the voltage further? It seems to play nice with my seeeduino mega but I wanted to be sure before I fry £80 worth of hardware on a hunch…

Thanks for reading, any help would be greatly appreciated!

Kind regards,

That looks like a sparkfun board:

The sell LiPo batteries that presumably plug right in.

Yes. According to the schematic you can supply it with up to 16v.

Here is a link to the connector you are referring too http://www.sparkfun.com/products/8670

Awesome, thank you both very much for the information :)

Shall go place an order with spark fun and await the arrival of my cables.

Kind regards,
