Dismantle the U-Shield of CCB [Copy link]

 

In response to the call for disassembly on the forum, I disassembled the CCB U-Shield. Some readers may ask, "Don't you want money? Why disassemble the U-Shield?" Don't worry, I'm not that stupid. This is useless. Front of the U-Shield Back of the U-Shield Scratched from the side Front of the PCB: Back of the PCB: It can be seen that there are two chips, one is CIU51256A, and the other is GD's 25Q32. The CIU51256A is from Beijing Huada http://www.hed.com.cn/CN/WebPage_51_77.aspx It can be seen that they are all domestically produced chips. I don't know if the LCD is domestically produced, but it's good that all the chips are domestically produced. The PCB is well made and the layout is reasonable. This shows that the author of the board has thought it over carefully. This content is originally created by EEWORLD forum user ddllxxrr.

Sometimes it is specified to be used.

The other day I saw an Agricultural Bank of China USB-Doubleton that I didn't use. It was outdated and not used by many people. I disassembled it because I was curious. The workmanship and shell were of good quality. The interior was the same as the disassembly diagram above. The layout and interfaces were very different.

It would be best to compare it with chips with the same function. The content of the pictures is general.
