Good news for RepRap makers, Zach writes –
I’ve finished two new versions of the boards for the Arduino electronics. These are incremental improvements that offer cool stuff like more blinky LEDs, minor fixes, and such. Full build pix, tester code, and everything you need to know to get started with these boards.
The DC Motor Driver board will control 2 small DC motors (or you could drive a small stepper if you wanted).
The PWM Driver board will control 3 channels of PWM at up to 5A each (theoretically) This is used for things like fans, heaters, etc that just need to be turned on/off.
The files are released on SourceForge, the boards are for sale in the RRRF store, and everything should be fully documented.
