About Grove
Grove is a modular, ready-to-use tool set that takes a building block approach to assembling
electronics. The Grove system consists of a base shield and a large selection of modules that
feature standardized connectors. The base shield allows for easy connection of popular
microcontroller devices to interface with the various Grove modules. Each Grove module
addresses a unique function & the overall collection of modules expand a wide range of
functionality - from a simple push-button to a complex heart rate sensor. Each one comes with
clear documentation and demo code to help you get started quickly.
About LaunchPad and BoosterPack
The Texas Instruments LaunchPad ecosystem is a set of low-cost & easy-to-use microcontroller
development kits that enable developers to rapidly prototype with modular, open source
hardware based on TI silicon. BoosterPacks are plug-in modules that can stack on top of the
various LaunchPad kits to add additional functionality, such as sensors, displays, wireless
modules & more.The Grove Base BoosterPack is a welcome addition to the
LaunchPad/BoosterPack ecosystem, enabling any LaunchPad to interface with the growing
offering of Grove modules from Seeed Studio. The Grove Base BoosterPack offers a
convenient and easy way for rapid prototypers to use more than one hundred Grove modules
with standardized connectors, including sensors, actuators, displays, lights, motors and more.
