2S/2P carrier and 6V LED can be used with normal parts up to 5A with lowered buck frequency
with upgraded parts about 8A
of course this might be well enough for a XHP50.2, but rather poor for a XHP70.2
Those are the currents to stay safe well within specification of the parts, of course it is possible to get out more but then no guarantee to operate without any issues over a long time,
if you want it just lower the sense resistors as usual for buck/boost drivers
I made a 30mm layout that could be extended in my board program to the nessesary size or grinding down the 42mm TN42
The Curoi should be 38.5mm, if the edge clearance is small the TN42 could fit
Got today the 2. batch boards along with more light types, was some delay from DHL because the content was just described as “boards” so they did not how to declare for import taxes
I am very happy with the quality of the boards better than last Chineese manufactory I ordered and cheaper too, multiple sizes of stencils cheap too
Especially the silkscreen is way better than last one that did not supported such small letter size which messed it up
