Hi there,
I have been in contact with Beta Board about manufacturing/purchasing a master board for the Solo 12 using the schematics/reference quote you provided. Unfortunately, the following parts are out of stock on Digikey/Mouser (at least in the EU/UK)/ they need clarification for:
· C10,11,12: the order number is for components in 0402. But as per BOM it should be 0805.
· IC2: is not available from Digi-Key. Please give us an alternative. (https://www.digikey.co.uk/product-detail/en/maxim-integrated/MAX17502EATB-T/MAX17502EATB-TCT-ND/5820948)
· L1: is not available from Mouser. Please give us an alternative. (https://www.mouser.co.uk/ProductDetail/Coilcraft/LPS6235-153MRB?qs=QQJxVsr8EGYwSUq1FFMxOw%3D%3D)
· U$4: is not available from Digi-Key. Please give us an alternative. (https://www.digikey.co.uk/product-detail/en/hirose-electric-co-ltd/DF13-6P-1.25DSA/H2195-ND/241769)
I think this may be a viable alternative for the Hi-rose connector: https://www.digikey.co.uk/product-detail/en/hirose-electric-co-ltd/DF13-6P-1.25DSA-75/H126408-ND/9170643
For the IC2, perhaps this:
https://www.mouser.co.uk/ProductDetail/Maxim-Integrated/MAX17502EATB%2BT?qs=Vwh6e7toGLgE6OAAxPIXhg%3D%3D
And finally for the L1:
https://uk.farnell.com/coilcraft/lps6235-153mrc/inductor-15uh-20-1-22a-shld-smd/dp/2408289?st=lps6235-153mrb
Do you think these parts will work? For the L1 it looks like the only difference is one is “Machine Ready”. I don’t know exactly what this means, but I presume it means it can be put into an automated machine such that it chooses things (i.e. it comes with some extra packaging). I suspect that this isn’t relevant if I’m still buying these one-off’s from Farnell, but I’m not super familiar with this.
