Forgot PD68 did the original BLF Q8 board layout, but under the guidance of DEL. Later on, DEL started doing and posting his own OSHPark driver designs, but using the same circuit design.

This is what ThorFire was given. Sorry, but the OSHPark listing has no details.
This is all of DEL's OSHPark listings: https://oshpark.com/profiles/DEL/page/1
This one of DEL's is pretty much closely matching what we have on the BLF Q8: https://oshpark.com/profiles/DEL/page/1
Differences are a different FET, bank of 7135's instead of 1, added a C3, and we don't populate R1 and R2. Matching ours: R3, R4, R5, C1, C2, D1. I think DEL's driver thread has some great reference info as well: https://budgetlightforum.com/t/-/44006. Check out post #3.
