Description: 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!

Customer Comments

  • The green LED’s seem to not be as bright as the others, is there a reason for this?

    Also, FANTASTIC pack. The kit was out of stock, and I didnt need everything in the kit, but I did need everything here. Fantastic deal.

    Only suggestion: include some female/femail headers and/or jumpers.

  • Gube / last year / 1

    In the photo there are 6 green LEDs and in the description it says there are only supposed to be 5. How many LEDs are there supposed to be?

  • If you thought this was a steal before…

    • Agreed. It’s got free photocells, motors, and servos, plus a better variety of LED’s compared to the other refill pack for the same price.

Best deal ever.

This is an amazing deal and I would recommend this to anyone who is low on components or is new to robotics because this is a great kit for an even better price.

OK kit

Motors and servos are really cheep. Way to many jumper wires. I would remove half the jumper wires, a couple of POTs and CDS cells and add 2 more switches. Also add 2 transistors or MOSFETs for speed control.


I picked this up to go with the Photon kit I got for my brother (before the PIK was available). Since there is SO MUCH STUFFS, I padded out my components a little, too.


The product was as expected. Quick delivery and was a big help completing my project.


Already possessing an Arduino Uno and a bit of expertise I found this kit grab-bag a very cost-effective way to start some new projects.
