Is M0 chip reliable? What is the difference between M3 chip and M0 chip? Tell me in detail.

The microcontroller uses M0 and the embedded system uses M3.

For example, M0 is equivalent to MCU and M3 is equivalent to ARM.

If you are just a single chip microcomputer, it is not recommended to use M0, the programming threshold is too high, and the development cycle is too long if you actually use it.

MEGA 128 is the most widely used film in this field at present, with reliable performance and low programming threshold.
