You can use either one. He describes it back in his first post under the 16mm oshpark link. It’s also in the descripition at oshpark.
If you are using the LFPAK33 that is.
Let us know how it goes Blue. I’m going to wait and see how your’s goes before I order any. I like the super capacitor idea.
I’m pretty sure you already know about Arrow’s free shipping. I order everything I can from them. Thought I mention it anyway.
BTW, I’m probably going to include the springs inside of the package if you don’t want/need a bypass, although not soldered for shipping not to explode.
A dual spring setup will easily be able to sustain 20A continuously.
Technically, it’s 21A for nickel plated, and 24A for silver plated, but it’s about the same number for me.
I already purchased all the parts for both the led and fet boards x 6.
Ordered almost everything from Arrow and a few pieces from Mouser. Mouser charged me 8 bucks for shipping for what would fit in a soda bottle lid.
