Power for Neopixel strip on Lily Pad

Community Projects

Hi Folks,

I’m hooking up a 1M strip with 30 NeoPixels to a LilyPad Simple. At full power, this LED strip could pull almost 2 amps. While I don’t plan to run them anywhere near full power, I’d like to design the project to handle it.

So I don’t plan to pull power from the Simple board, but want to connect strip to the 2000 mAh LiPo.

Question…is there a solder point after the power switch I could do this, or can I splice into the battery lead? Is soldering to the board to a switched pad possible?

Thanks

I think you’ll need to splice into the battery lead. I found a test point (TP) on the LP schematic that supposedly connects to the LiPo input but it’s a small via and I really really doubt the trace to that via could handle 2A.

As for a point after the power switch … I don’t know. There’s a big + pad (so labelled) on the LP outers circumference but I have no idea what it’s connected to to.
