Even though Arduino Education kits are jam-packed with everything you need, we know that mislaying parts in the excitement of getting hands-on in a classroom can sometimes happen. In the Arduino Replacements Pack, you’ll find all the common electronics parts students may need to complete their projects. This pack has replacement parts for the Arduino Starter Kit Classroom Pack, Arduino Student Kit, Arduino Education Starter Kit, Arduino CTC 101 and ARDUINO CTC GO! – CORE MODULE. The pack contains a total of 183 replacement parts, including a breadboard, jump wires, LEDs, resistors, transistors, sensors, and more. Note that for larger products such as CTC GO!, you may need more than one pack of replacement parts.
