An overview of the MicroPython kernel

The MicroPython kernel is a collection of software libraries, code, and a Python interpreter that comes pre-built on a MicroPython board, such as the pyboard. Someone who is new to MicroPython may not even realize that their Python interpreter is made up of C modules. These modules are compiled and then programmed onto their board, which then reveals the filesystem and REPL that we have become so familiar with. In this chapter, we are going to look more closely at the kernel and explore how we can make our own modifications that will enhance our applications.
