Boost or buck/boost driver that outputs ~500mA is easy. Buck/boost that puts out 3A or more and fits in a 17mm hole is a different story. This has been the subject of several threads already to come up with a design that could be commissioned, it always ends with 'well it's just not possible to fit the components into the given space'.
Just a note before you post:
The primary intent of this thread is to assemble a focus group for hardware design and manufacturing and is specifically directed towards members interested in and capable of working together to solve this challenge. This is not meant to offer ideas of UI features, such as mode selections or voltage cut-off, etc. Please allow our pool of BLF extraordinary talent to colaberate. I ask that you withhold any unrelated comments to maintain focus… if that is even possible…
Bill Zeng sent me an email asking for specs on a Custom Build Circuit Board for BLF. Here is your chance, give me the specs…
So far this:
Hi Flomotion
tomorrow i will get 2 samples driver
at the mode: 100% - 35% - 10%, working current at 5A(the 3.7V battery must be good),3.7~4.2V
it can work on U3 and XM-L2 led emitter too
also please let me know what circuit board you need
i will make them separately for you
yesterday,i test the board at factory,i installed it with a U2 led emitter,and …
