CK_LINK Lite2.30

Based on QQ group SW: CKLinkLite2.30, CK_Link Lite
 
directly modifies ST LINK V2. The color of the schematic diagram indicates the modification of pin definition. The real thing is as shown in the picture, it has become CK_Link Lite. Works perfectly. 
 
 
After drawing the picture for a long time, the last two lines really didn't make sense. I couldn't hold it back, so I created a 4-layer board (Lichuang is also free), flew the wires directly, and then simply removed the power supply from the inner layer, and I didn't have the energy to optimize anymore. 
 
This time, Lichuang probably thought my board was too small and gave me 6 yuan. 
I saw that there is an open source CKLinkLite2.30, there is one on Lichuang. After reading everyone’s comments, I think it is quite good. So, I prepared to use ST LINK V2 to transform it. After reading everyone’s comments, I think it’s too big, so I’ll make a smaller one. Basically, all the parts of this ST LINK were transferred, and LEDs were added. The principle is borrowed from the QQ group information. I looked at the QQ group and Lichuang open source and thought that Lichuang's is more reasonable. At least there will be no direct inversion of power and ground. No need to talk nonsense, everything is working normally. Debugging is also normal.
 
 
Note: My output is 5V, the purpose is to directly power the development board. Avoid inserting so many heads. 
 
Everyone can modify it according to their own needs and make a prototype.
