Desktop Power Supply

Based on the original author's design (improved desktop power supply), the two original XT30 output ports were removed, and some changes were made to the output and input interfaces:
1. A USBA interface, a set of 4P pin headers, a set of 4P female headers and two reserved pads for welding alligator clips were added on the boost side and the buck side respectively.
2. The original author's input DC interface was modified (because I don't have the big brother's, I replaced it according to what I have on hand)
3. The resistance values ​​of R4 and R1 in the original author's project were modified:
Original author: R4: 18.7K, R1: 12K
After modification: R4: 3K, R1: 1K (The modification was only because it was found that the voltage regulation range was small after the production was completed, so a smaller resistance value was used to increase the voltage regulation range). The modification here can be ignored by the creators, and the original author's resistance value is used for welding. If you encounter the same problem as me, this modification method is for reference only.

5. For schematics and other detailed information, you can move to the original author's article, which is very detailed. I only provide the modified PCB file.
Note: Only the PCB file is for reference, the schematic is not for reference and the schematic is not related to the PCB. If you refer to the schematic, please move to the original author's open source link.
Thanks again to the original author for the open source.
