tarter Kit with free Course for all Electronics Neophytes and Enthusiasts
Seeed Studio has provided the Grove Starter Kit along with free and detailed courses for you quickly get started with microcontrollers and electronics, regarding all the Seeed Studio XIAO boards, promising you a great learning experience.
Not only programming but also electronics knowledge is not required, you will be taken step by step, from understanding the basic concepts to exercising the simple projects individually, finally being able to build complex, interesting, wearable projects on your own, owing a practical electronic product prototype from the course.
You can have access to the Seeed Studio Grove ecosystem by connecting it to the compatible Seeed Studio XIAO expansion board. We have developed more than 400 Grove modules, covering a wide range of applications that can fulfill various needs. For example, you can make a BLE AI-driven Smartwatch Detecting Potential Sun Damage by connecting the Seeed Studio XIAO nRF52840 with an expansion board, and a Grove - UV Sensor. Get started and explore the infinite possibilities of the Seeed Studio XIAO series!
If you are interested in programming embedded machine learning, we have Codecraft visual programming that can help you quickly start your own TinyML project. And we have set up a #tinyml channel on our Discord server, please click to join for 24/7 making, sharing, discussing, and helping each other out.
We already have 10 XIAO products based on different solutions in the XIAO family, to help you better understand the differences and choose the most suitable part for your projects, please refer to the Seeed Studio XIAO Series Page.
