Don't buy it. Raspberry pie is for people who are experienced and like to toss. It is not recommended for beginners.

1, if you want to learn linux and C language, you can just install a virtual machine on an ordinary computer.

2. If you want to learn embedded, you can buy an ordinary ARM development board to learn.

If you just want to get in touch with it and have fun, and there is no actual project to operate, you must eat the dust.

I hope it can help you!
