【ATRI】MEGA2560 Personal use version

# Introduction

###### Mainly I want to try the color screen printing effect created by Lixin. For the sake of simplicity, the PCB design of 2560 directly uses the open source project [[Lonely Rock] MEGA2560 Color Silk Screen Development Board] (https://oshwhub.com/aknice/mega2560-demo) on Lichuang, and I redesigned it myself I took the silk screen picture (for the sake of better appearance, I deleted all the screen printing of components and soldered directly according to the schematic diagram), and customized a batch of special colored pin and female headers to make the overall color of the board more coordinated, and used UV transfer stickers to Implementing pin silk screen printing frees up a larger board area for my wife.

# Color silk screen design
###### Referring to the layout design of the original project 2560, we decided to use a simple color matching design, and the colors were taken from Atori's clothes The blue is paired with white and a touch of red. The edges of the component pads are also outlined in blue. There is a whole space on the back to fit a whole large picture, which is very effective, and there are a few emoticons in the extra space.
###### All silk screen files will be placed in the attachment.

### Pin screen printing
##### # In addition, I transferred all the pin screen printing to the header, and specially customized a set of UV transfer stickers, and the files will also be placed in the attachment. This allows us to place larger images and effectively utilize the free area on the pin headers and headers.

# Summary
###### Generally speaking, Jialichuang color silk screen printing control Not very stable. My classmates and I did color screen printing three times, and found that the screen printing effect was good and bad. For example, this time the screen printing on many pad positions was crooked (a great tragedy), but once it was printed very correctly, it depends on luck. . The clarity is far from satisfactory. Overall, the effect is quite good. After all, 30 pieces of color silk screen and immersed gold is a problem for me.

###### **The crooked silk screen is indeed only a little crooked, but it is indeed crooked**
