## What are these?

NeoJoints make it easy to solder together pieces of WS2812 / NeoPixel-style

LED strip.

NeoJoints have the following features

* Available in multiple angles

* Solderable holes for adding additional power at joints

* Cuttable trace on data line for separating strips logically

* Mounting hole for 2-56 screw

* Single-sided millable on PCB mill like Othermill,

    with a single 1/32" endmill (though adding 1/8" to cleanup helps)

## How to Solder

* Step 1: Get NeoJoint and LED strip pieces laid out correctly

  - Be sure to make sure data arrows are pointing correctly

  

* Step 2: Turn over strips, put small solder blobs on *back* of each pad

  - Depending on the strip, you may need to scratch away adhesive layer or waterproofing

  

* Step 3: Lay strip on top of NeoJoint, then heat up with soldering iron to melt solder blobs, one by one

  - Take care to keep strip aligned when melting first solder blob

  

* Step 4: Continue until you've soldered down all points

  - You can look along the side of the strip to see if the solder has melted

  - And you can see if you have any solder bridges
