Please review design of controller for Peltier

Has anyone used these two boards together?

Freeduino Motor control shield from NKC Electronics: http://www.nkcelectronics.com/freeduino-arduino-motor-control-shield-kit.html

Bare Bones Board kit from Modern Device: http://www.moderndevice.com/products/bbb-kit

Can anyone tell me whether they are likely to play nicely with each other?

(Yes, I know I'm showing my ignorance of Arduino standards here. I think that, according to the specs, they are supposed to work together. But I'm unsure enough that I'd like to have someone more knowledgeable than me reassure me. Thanks.)
