CPU DIY Kit TD4 CPU Make a Simple 4-bit CPU By Yourself Open Source Software and Hardware PCB and All Components Optional

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
