Arduino Nano Addressable LED Case

thingiverse

This is a tiny compact case that I designed to hold an Arduino Nano and a 3 pin JST SM connector for controlling addressable LEDs. The case is made for the JST connector to fit quite snuggly, but a drop or two of super glue can be used to fully secure the connector in place. I wired mine to be used with 5v addressable LEDs by connecting the following: JST + to Arduino 5V JST data to Arduino GPIO 11 on ICSP JST - to Arduino GND If using with 12v addressable LEDs then connect as follows: JST + to Arduino Vin JST data to Arduino GPIO 11 on ICSP JST - to Arduino GND Inspired by [Nisimoto's](https://www.thingiverse.com/thing:3313487) design, the small holes in the lid of the case show the Arduino's status LEDs. To make light guides the locking pins of four RJ45 plugs can be inserted from the bottom and cut flush. The USB port of the Arduino Nano is easily accessible allowing for quick changes or updates to the code. If keeping the power draw low by limiting the max brightness of the LEDs the USB port can also power some 5v addressable LEDs. If more LEDs or greater brightness is wanted then the addressable LEDs can be powered directly and the JST SM connector can back feed power to the Arduino eliminating the need for USB power.
