Introduction

Raspberry Pi is a delicate card computer. This is a starter kit of Raspberry Pi, very suitable for zero-based raspberry pi enthusiasts. Through this kit, you can learn more about the knowledge of linux operating system, as well as C, python and other language programming based on the debian system of Raspberry Pi. This kit also provides you with some related sensors and modules applied to the Raspberry Pi .
We offer richer learning materials that allow you to learn about Raspberry Pi from scratch. The learning materials include the installation and usage of the Raspberry Pi related system, where also offer you the learning courses of Raspberry Pi collocated with some commonly used sensors and modules. It would be better If you are an arduino hobbyist because arduino and Raspberry Pi are the best partners. You can make more creative DIY works via arduino strong community support and rich third-party library resources, integrating into Raspberry Pi's powerful function support to motivate your creativity and inspiration!
