Note

1. It’s better to solder the Micro-USB first when soldering the components . If you solder other components first, the Micro-USB would be blocked and very difficult to solder as it’s small.
2. Please pay attention to the silk screen notch mark on the board when insert the chips into chip sockets, otherwise the chips may be burned out if they are inserted reversely.

Introduction

By making a simple 4 bit CPU with complete functions by yourself, you can systematically understand digital circuit logic, timing, assembly language, hardware and software, and have a deeper understanding of the essence of computers.
