About SunFounder EC-Block Analog Kit

EC-Block is an electronic building block product newly released by SunFounder. After years of serving open source electronic hobbyists, we decided to release an easy-to-use product to lower the threshold for the field of open source for numerous hobbyists, so you may experience the fun of open source electronics in a quicker way!

Just like building blocks, EC-Blocks can connect with each other. Each building block has a built-in circuit. These building blocks can be categorized into power supplies, sensors, converters, and outputs by their functions. Each type of building block uses different colors. The name of each block starts with some mark, which represents their types and functions. You can quickly find and recognize a building block with its name. These building blocks are designed for high flexibility. You can build them together as you want regardless of number and type. All the building blocks in this kit are based on analog values, which mean they can output different values or make different reactions.

For higher flexibility and more fun in free combinations, Arduino-based blocks are added. It can be used just like other ordinary Arduino boards and connected with all the blocks in this kit. With different connections and code, you can feel the great charm of Arduino free from complicated wiring.
