We have designed a simple break out board for the MP3V5010DP pressure sensor which comes with its own low drop out voltage regulator (MCP1703) so you can power it with e.g. 5V instead of the needed 3.3V. Additionally there is an OpAmp (MCP601) on board to add some arbitrary offset (0-3.3V) and gain(1-2x) to the sensors analog output via two trim potentiometers. All the components are SMD, which makes the board dimensions rather small (20x40mm), ideal to fit into nice casing.
