The Centimani Servo Power Board
This project was my first foray into developing detailed documentation.
It was in response to a contest held by Nick of GadgetGangster.com. I
also posted the board on his site (GG) in hopes that somebody might buy
one (and I get a cut of the price). So far, that hasn't happened but I
have come away with an appreciation for the amount of work
documentation takes. |

From the Documentation
The Centimani Servo Power Board (CSPB) is a high current and low cost solution to powering servos. Many microcontroller development boards come with onboard regulators to provide power. Such boards include the Parallax Board of Education and the Parallax Propeller Professional Development Board. However, these regulators are usually rated at up to one amp. When running many servos, the current draw may be too large and problems will arise. The CSPB provides four additional 3A regulators to power your servos from an external power supply. Note that the CSPB does not generate any sort of servo signal. Please also note that the CSPB requires a power supply that can source up to 12 amps and that is within a few volts of 5V. A 7.2 volt RC car battery would work very well in this application.
