Issue: Is there any chance that I can find the diagram for U2D2? We want to customize it a little bit and make it smaller

I am sorry. It’s U2D2 power hub diagram that we need
I am not sure of exactly what you are looking for, but if you are looking at an alternate way to power your DXLs, and you have a good reliable Power Supply, then you can just use these types of DXL hubs (4-pin) and (3-pin) and prepare just a special cable to go from your power supply to these DXL hubs (i.e. VDD and GND). You can continue to use the U2D2 to control your DXLs, as VDD is not connected to the U2D2. The U2D2 does need to have a COMMON GND with your power supply module. The U2D2 uses the DATA Line at 5V TTL to send/receive DXL packets from your hardware controller as normal.

In the past when I was not sure about the quality of my Power Supply, I also used capacitors between the VDD and GND lines, as suggested by ROBOTIS
