Prototype 20A converter, in progress.  Still waiting on a couple of components.  This costs $30.  If it works as expected, I'm going to order parts for a bunch of them.

I'd rather have Arduino shields.  But it looks like there isn't enough interest to get that done.

Sorry mate. Havent checked on this thread for a while.
Iv'e got a little time at the moment so I can do a little more testing. I am going to re-design the board again and make a few little changes.
I'm going to get rid of the hall effect sensors as they are not very accurate and drift alot!
I'm also going to move the pins around and increase the capacitance. You will be able to jumper any PWM pin to the mosfet driver.

Hi antman,

would you please share the schematic for your buck converter?

Is it possible to connect the output of these in series?

Thanks.

Hey Antman,

I'd also be really interested in your schematic. I had a project to build a peltier driven  heating and cooling device that has largely floundered because of the design and (mostly) assembly of the buck converter. A schematic for this would be really helpful.
