The basics behind the batteries used in portable electronic devices: LiPo, NiMH, coin cells, and alkaline.

The SparkFun ProDriver and Mini Stepper Motor Driver boards utilize Toshiba's TC78H670FTG stepper motor driver. The ProDriver features latch pin terminals, which are easier to connect than the "Easy" Drivers. Meanwhile, the Mini Stepper Motor Driver come in smaller PCB footprint, that is pin compatible with breadboards. To get started, follow this hookup guide and you will be spinning stepper motors, in no time.

Connectors are a major source of confusion for people just beginning electronics. The number of different options, terms, and names of connectors can make selecting one, or finding the one you need, daunting. This article will help you get a jump on the world of connectors.
