What is Grove?
Grove makes it easy to connect, experiment and simplify the prototyping process. No jumpers or soldering are required. More than 300 Grove modules have been developed to cover a wide range of applications and fulfill a variety of requirements. Not only the hardware is open source, but also the software. Instructional PDF documents and a wiki are provided for Grove users (especially beginners).
We offer various Grove Shields to enable connection to the Grove system with various microcontrollers.
