Raspberry Pi refers to a hardware that is open source. Raspberry Pi is a finished development board with CPU and memory on it, but they all exist in the form of discrete chips, and the CPU performance far exceeds that of single-chip microcomputers and can run Linux operations. system. It can be said that it is a very popular small computer system, and its essence is also a development board. Its chip is Broadcom's BCM2835 chip. This chip uses the aforementioned ARM architecture. Most of the things in your computer case are integrated into a microcomputer on a circuit board, connected to a monitor, mouse, keyboard, etc. There is no substantial difference from your computer. The operating system is different. This is a linux-based system.
Single chip microcomputer is a general term for a type of chip, which integrates CPU, memory, Flash (analogous to the hard disk of a computer, the early single chip is ROM) and peripherals such as IO on a chip. It cannot run a time-sharing operating system such as Linux or Windows. .
The single-chip microcomputer can have more than ten PWMs, but the Raspberry Pi only has one PWM.
There are also microcontrollers that can't do it, but the Raspberry Pi can do it, such as taking pictures with 500W pixels, running minecraft, etc.
Raspberry Pi: Mini Card Computer
Single Chip Computer: Single Chip Computer
Many times the Raspberry Pi is powerful because of the addition of many expanded peripherals. From the point of view of chip capabilities, there are still many things that cannot be done.
