General Description
The Hitachi H48C 3-Axis Accelerometer is an integrated module that can sense gravitational (g) 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 breadboard-friendly, 0.7 by 0.8 inch
module. Acquiring measurements from the module is simplified through a synchronous serial interface.
With the BASIC Stamp
commands.
