The steering diodes can be oriented either way depending if you need faster turn on or faster turn off. Most of the time you want faster turn off and slower turn on to avoid dv/dt spikes.
Where is your 5v power supply? the arduino in your picture will not provide enough 5v current to start up the dc dc converter. Look at the silkscreen on the pcb. You need 5v dc, ground and a 5v pwm signal.
