Altium Designer - schematic diagram of Arduino uno & PCB diagram (self-made Arduino board)

This article is based on Altium designer Software drawn Arduino UNO Schematic diagram of minimum system circuit &PCB chart , Close test available , See the link at the end of the text for the complete circuit document

Arduino It's easy to use , Friendly for beginners , A simple few lines of code can achieve a demo function , But the existing arduino The plate shape is relatively fixed , Specific applications in the project need to design their own circuit boards based on chips , See the following for the detailed implementation process

（1） System schematic diagram

（2）PCB chart

self-control arduino The development board is based on ATMEGA328p Chip implementation , The empty chip state needs to be loaded first bootloader To work properly , About loading bootloader See the following link to this article , There is a detailed introduction
