I didn't do any comparisons yet between the schematics, but will these BOM's work?

If you want order from pcbway, order from the link provided, that way i will get some commission . You can also change pcb specification of pcb if you so desire. pcbway charged me 15 usd shipping. + 5usd for pcb + there will be some customs duty of about 1100-1200 INR by our overzealous customs.

The link for placing order is in below post.

Schematics almost same, but bom may not be valid for this design as I have used some other packages for some resistors and caps, (e.g. input caps , electrolytic caps, ceramic caps, etc). Also inductor is hand made in this design. I can give you parts list with dimensions.
