First, the subject is different.

1, Raspberry Pie: It is designed for learning computer programming education. It is just a microcomputer the size of a credit card, and its system is based on Linux.

2. Single chip microcomputer: It is an integrated circuit chip, which integrates a central processing unit (CPU), a random access memory (RAM) and a read-only memory (ROM) with data processing capability by using VLSI technology.

Second, the characteristics are different.

1, Raspberry Pie: Microcomputer motherboard based on ARM, with SD/MicroSD card as memory hard disk. There are 1/2/4 USB ports and one 10/ 100 around the card motherboard. Ethernet interface (type A without network port), which can connect keyboard, mouse and network cable. At the same time, it has a TV output interface for video analog signals and an HDMI high-definition video output interface.

2. Single chip microcomputer: The volume of single chip microcomputer is relatively small. As a computer system, the internal chip is simple in structure, perfect in function, very convenient to use and modularized.

Third, the function is different.

1, raspberry pie: provide the distribution of Debian and Arch Linux based on ARM for the public to download. There are also plans to support Python as the main programming language, Java and BBC BASIC? Programming languages such as c and Perl.

2. Single-chip microcomputer: Single-chip microcomputer has strong data processing ability and calculation ability, which can be applied to various environments and has strong control ability. Single-chip microcomputer is the first choice for people's daily life because of its low voltage and low energy consumption.
