Re: RAMPS for Due!

Thanks for your answers mates. And I hope my questions aren't OT. If so I'll open a new thread.

bobc: Well I'm happy that my question gave you a reminder about the external connection of step drivers. Also the check about servos.
On the THB6560AH side, I've found out the original author of that board which luckly is in Europe (I'm italian) so I can buy easily. He sells that board in two versions "traditional" and "special", they have small differencies from the one I linked above.

Traditional version:
- Larger PCB (50 x 100mm).
- 4 current sense resistors to reduce their power and heat dissipation.
- Amplifiers on the output signal of the optocouplers, this will allow the drive to function properly with low current input signals.
- Seperate ground plane for signal and power.
- On board space for voltage regulator heatsink.
- On board space for THB6064 heatsink.
- Easy mounting with 4 fixation holes in each corner.
Special version:
- Smaller PCB (50 x 50mm) reduces cost.
- Driver chip is located outside the PCB for easy mounting on the heatsink.
- Fewer or combined components further reduce cost.
- 2 current sense resistors.
- Unlimited heatsink size for easy chip cooling.

So, dear masters, which components do you suggest to change/remove to give it compatibilty to the RAMPS-FD? :)
I choose this Toshiba component because I was looking for a good Ampere driver, I think that this step driver is good for parallel wiring the step motors as it give up to 4A. Mine RepStrap has dual step motors system on the Z and X axes, so I can save one or two step driver outputs on the controller board. My plan was using the RUMBA or RAMPS and I didn't think about 3.3v when I saw the RAMPS-FD. That's the reason I asked my first question. Thanks for your good work on RAMPS-FD!
