The Hitachi H48C Tri-Axis Accelerometer is an integrated module that can sense gravitational force of ±3g on three axes (X, Y, and Z). The module contains an onboard regulator to provide 3.3-volt power to the H48C, analog signal conditioning, and an MCP3204 (four channel, 12-bit) analog-to-digital converter to read the H48C voltage outputs. All components are mounted on a 0.7 by 0.8 inch module. Acquiring measurements from the module is simplified through a synchronous serial interface. With the BASIC Stamp series, for example, this is easily handled with the SHIFTOUT and SHIFTIN commands.
We do not recommend using this module with a breadboard. The design has fairly short pins with components on both the top and bottom of the module. A permanent mounting location on a through-hole board like the Parallax Super Carrier Board is the only mounting solution we support for the Hitachi H48C Tri-Axis Accelerometer.
