Unipolar stepper driver SLA7062M Shield MEGA

Hi,

I did some schematics and begin the board layout.
Included this post you can find a download link to EAGLE(5.10.0) board and schematics files.
I'll hope that someone finds this usefully!

Boards is almost finished, i let some components free so anyone can layout those in the way they want!
This will only need 4 arduino I/O pins and ground + external VCC(12-40VDC) and GND.
1/2, 1/4, 1/8 and 1/16th steps can be set by two jumpers.

SLA7062M is a unipolar steppermotor driver chip what can do 40V & 3A per coil with proper cooling. (remember to place the SLA7062M chip to edge of the board so the cooling element can be applied.)

All I/O's to arduino are opto-isolated!

This board actually left behind, i ordered few bipolar stepper boards what i made (up to 42V and 2A / phase (4A)). Gotta see what they're looking like.

Next step is to lay components to arduino UNO shield.
When i accomplish that, i will post all files here (including files for the BatchPCB-service).

But first gotta wait at get the protoboard.

I'l hope that 42V/4A-powered stepper board would be interesting for some projects.
If not the addon shield, i can also post the "off-shield" so you can connect 3-4 drivers to UNO for example via screw shield.

In the mean while this is what i am waiting. Note that this is not yet tested in real life!
