VoltroveMIC1557 is now available with RPP! It’ll auto fire in a reverse polarity condition, but won’t affect anything.

Proteus project file: https://drive.google.com/open?id=10_gWsq2oYxhuZroiCzH90-YV88kyd1HZ

Input range = 2s-4s. Switching Frequency = 280hz

“How low can I build?” You want to build higher and use the voltage. That being said, 2s = 0.15 3s = 0.2 4s = 0.3

Board has markings for 0, W(wiper) and 100 pins on the popular 93 series pots. There’s pins behind the 0 and 100 on the pot and the wiper is in the middle.

Fire switch should be wired between BAT+ and VIN+.

License: Free for all! Build ‘em, sell ‘em, whatever you want. :)

I recommend getting 2oz boards if possible, but 1oz would work.

Digikey cart is setup for enough components for 3 PCBs.

The top and bottom stencil files are in the gerber zip. Simply download the gerbers and order stencils from OSHStencils or wherever else you like.

Feedback is welcome.
