It's based on the second version of the pcb, the one with the DRV8834 stepper driver.

Bill of material:
1 x DRV8834 stepper driver
1 x ULN2003A
1 x 47uf 25V capacitor
1 x 100uf 25V capacitor
2 x 5V line laser (I recommend those rated 3V to 5V)
1 x transformer 5V 3A
1 x stepper motor Nema 17 5V
1 x Raspberry Pi 2
1 x Raspberry Pi camera module v1.3 (not shown in diagram)
