Topic: Working board diagram for the new low voltage DRV8834 driver with BOM

Here's the latest board diagram tested and working.
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)
