Nwazet Key Lime Pi Wire Scorpion Bundle Assembly Instructions

Introduction: Nwazet Key Lime Pi Wire Scorpion Bundle Assembly Instructions

This is a quick guide on how to assemble the scorpion bundle for use with the Raspberry Pi.

"We just released our 'Key Lime Pi' breakout board which adds eight 10-bit analog inputs, converts the Pi's serial interface into a standard FTDI connector and allows for external power headers to be added if desired (standard 0.1" pin headers and JST-PH vertical header)." - raspberrypi.org

"Analog readings are as fast and accurate as possible, thanks to the Pi's SPI interface (hardwired to CE0), a proper ground plane and a stabilized ADC power supply. If more than eight analog inputs are needed for a project, chaining to another 'Nwazet Key Lime Pi' board is possible by interconnecting the GND, MOSI, MISO, SCLK and CE1 lines with jumper wires.For prototyping, the 'Key Lime Pi' board maximizes the real-estate available on small breadboards by hugging the center divider, leaving four rows out of five available for wiring. For embedding a project into a permanent fixture, the board features three mounting holes, placed on a standard 5mm grid." - raspberrypi.org

"The 'Pi Wire Scorpion' kit is designed to provide a practical enclosure for the 'Nwazet Key Lime Pi' breakout board (included). Use it as you build your project or as part of a final installation: it will do a great job at securing wires in place thanks to nine built-in zip-tie cutouts. The 'Pi Wire Scorpion' kit accommodates all the features of the 'Nwazet Key Lime Pi', works well with right-angle and straight pin headers and includes all the essential cables and connectors needed to complete your project quickly and neatly." - modmypi.com

Step 1: Placing Components

Step 2: Tape the Components Down and Solder

After soldering, inspect to assure that there are no bridges or other flaws. Place IC.

Step 3: Plastic Covers

Peel away the layers on both plastic pieces. Then take the 3 Hex spacers and attached them to the bottom with 3 small screws.

Step 4: Top Cover

Align the board's 3 holes with the Hex spacers. Place the remaining 3 spacers on top of these holes. Carefully place the top so that the holes are still aligned. Insert the 3 remaining screws and turn until tight. Place the 4 rubber feet, one in each corner.

Step 5: Plugging in Wires

Either separate the ribbon cable into sets of 4 wires and then plug into the board. Or plug them all directly into the board and then separate. There will be two groups of 5 wires. Lastly zip tie the wires together and to the board then cut away excess material.

Step 6: Final Step

Plug in your remaining wires and you're done.

    I made it, and I'm OK with the results, but I wish I had considered a different build option before soldering. If I had soldered the two 16-pin headers to the underside of the circuit board, and not used the plastic pieces, I could mount it directly into a breadboard. That has several advantages.

    - I could move the Scorpion from one breadboarded project to another without disconnecting individual wires.

    - I could use only the wires that were necessary, reducing clutter.

    - The pin labels would be easier to see because of not viewing them through the plastic.
