I have a robot that requires six h bridges to drive Firgelli linear actuators. What I'm looking for is a shield/board/etc that will save me the trouble of building them each myself. The boards I have don't give me the fine-grain speed control I need.
If you know of an existing solution that will simplify my life, please respond.
Thank you so much!

Any specs on the actuators? Voltage, max current, etc...?
If current requirements are under 4 amps for each actuator - there are plenty of L298 interface PCBs and shields available (but since you need more than one, a shield likely won't work for your app). Each L298 has 2 h-bridges of 2A each (2 motors); or can run in bridged mode (1 motor, 4A). If under 600mA - 1A, there are L293 PCBs and shield that could be considered as well (2 motors per). Note that on both of these if you are running anywhere near the rated current capacity, you -will- need heatsinks.
