SLA7062/67 Step Motor Driver

The SLA7062/67 chip is a unipolar driver and can provide up to 3amps. The chip is hard to find and will cost about $10. each. Using Google, I found the three that I needed for my prototypes. Newark (Farnell) sells them but has no stock. The pcb's can be purchased from Batchpcb and below find the BOM and the circuit diagram. This board uses the 10 pin IDC connector (PMinMO) and is compatible with the CNC USB Motion Controller.
