One more update by OneOfEleven, he send me me this:
Found some errors in the schematic nqtronix and added the component values as well. This should now be the final and correct schematic ..
Another helpful update by OneOfEleven:
Your PCB looks to be a 2014 version, mine appears to be a 2018 version (only difference is R1 & R20 I think). Here's a piccy of mine you could add if you wanted to help others.
OneOfEleven has created a correct and complete schematic of this module, you can find it in the project files or below. Thank you for sharing this!
By chance I found another post about this dcdc converter with in-depth measurements. Check it out here: https://lygte-info.dk/review/Converter DC-DC 10A 8.5-48V to 10-50V 250W UK.html
