The SparkFun Inventor's Kit (SIK) has been and continues to be a staple for classrooms, workshops, and makerspaces for over 15 years. But when many hands share the same hardware over a semester, small components inevitably get lost or broken. Instead of replacing an entire kit, the SparkFun Inventor's Kit Refill Pack is a simple and economical solution to replenish your stock and keep your classes running smoothly. This pack targets the most common, wear-prone, and easily-lost parts from our Inventor's Kit. Inside the included protective carrying case, you'll find the components that see the most action or are hardest to find in a messy bin, including servos, simple sensors, a fresh supply of multicolored buttons and LEDs, and more! While designed as a refill, this pack also works perfectly well as a standalone parts kit. It offers a great selection of standard components for any electronics project, even if you don't own a SparkFun Inventor's Kit. One Pack for All Your Kits We designed this refill pack to be a universal solution for our most popular educational kits. It's the perfect add-on to keep your inventory complete, whether you're using one or all of the following: * SparkFun Inventor's Kit * SparkFun Inventor's Kit for MicroPython * SparkFun Inventor's Kit for Arduino Uno * SparkFun Inventor's Kit for micro:bit * SparkFun Tinker Kit * ...and more! Don't let one missing part derail a lesson plan. This refill pack ensures your SIKs and Lab Packs are 100% complete and ready for the next group of curious inventors. https://elecena.pl/product/16392476/sparkfun-inventor-s-kit-refill-pack 2020-04-03 https://elecena.pl/product/16392476/sparkfun-inventor-s-kit-refill-pack 2022-11-08 https://elecena.pl/product/16392476/sparkfun-inventor-s-kit-refill-pack 2022-11-16 https://elecena.pl/product/16392476/sparkfun-inventor-s-kit-refill-pack 2023-03-06 https://elecena.pl/product/16392476/sparkfun-inventor-s-kit-refill-pack 2023-03-12 https://elecena.pl/product/16392476/sparkfun-inventor-s-kit-refill-pack 2025-03-24
