Yes! 144v 500amps! It is a lot of power, huh! But these components can take it.
Atmel AVR Studio
It's a free development environment and C/C++ compiler/editor. Then you just go up and click to program the microcontroller from inside the editor! It's all self contained! It's awesome. I think they do it so you will use the AVR microcontrollers instead of PIC.
I am in communication with a company for a really good deal on diodes. They sell them for $2.36 each, whereas Digikey and Mouser both charge like $5.19 each, and since you need 10 for a 500 amp controller, it is quite a bit of money! It takes like $20 off the price right off the top. I was looking at components, and if people would get kits in groups of 2 or 3, the parts costs are around $250! Isn't that amazing!?
