Buck Gizmo -Volts vs Amps ? UPDATED
Update 5 Nov. (It didn't work out as hoped)
I got my little gizmo, see close-up photos here

It is tiny! 2" by 2 3/8" Solidly built though. It has a few two-hole connection points on the board as seen in the photo, one is called "Key" What is that for? Thanks.
When I get to testing this I have been thinking I can use my two trickle float chargers as input to simulate a solar panel with the voltage inside the range of the gizmo.
Each charger is 2 amps and makes 14.2-13.4 volts , floating at 13.4 steady. So I think I could put them in series and get about 28 volts and 2 amps to feed the gizmo, then it should have about 4 amps at 14v output?
I will also try it on the 37 volt solar panel once I get its voltage down a bit (shading a cell or two ought to work) so it won't fry the gizmo.
(This was all just to explore the part the buck converter plays in an MPPT controller. I haven't thought of anything this gizmo could do that I can't do now with other equipment, but maybe something will occur)
