If you use the SparkFun Inventors Kit in a classroom or workshop setting, you know that when a bunch of people get their hands on the same kit, things get lost/broken. That’s why we offer the SparkFun Inventor’s Kit Parts Refill Pack. This way, you don’t need to buy a whole new kit if you lose a few of the smaller or more wear-prone bits.

This refill pack includes new items such as servos, gearmotors, photocells, and mutli-colored buttons and LEDs. We understand that sometimes you need to replace some more pricey parts, we hope this helps!
