I don't understand the difference between a motor-driver like this IC H-Bridge Motor Driver and a motor-driver like this Dual Motor Driver Board. When reading about them they do the same thing but the second one is obviously much more complex and more expensive.
Item 1 - The L293 has two H bridges and is a chip.
Item 2 - The Ada fruit product is a circuit board with two chips and each chip has a single H bridge.
Item 1 and item 2 are functionally very similar however Item 2 has H bridges that are superior.
Item 1 is a chip that needs soldering to a PCB and item 2 is a PCB with broadly the same functionality as Item 1.
