== Design Tradeoffs ==
 +
* Making each board fully functional as a stand-alone kit makes the complexity / price of the Sabre more expensive
 +
* Using a networking protocol like i2c vs. shift registers or direct wiring or charlieplexing provides more flexibility, but also more complexity
 +
* The LED density increases resolution, but increases cost and complexity
 +
* Adding a wireless protocol like wifi or bluetooth allows multi-sabre connection (BATTLE!) but makes the sabre more expensive
 +
* More LEDs / Higher Brightness LED = more current = larger battery (size / weight considerations) or shorter battery life
 +
* Is the Sabre a product? Are the individual boards a product? Is the goal to have fun & learn, or make money? - they may be mutually excusive
 +
* Through-hole construction makes for a better kit, but drives size / cost up
