Application Note INVARM User Guide PURPOSE This document describes the hardware, connectivity and circuitry for revision G of the InvenSense ARM Controller Board (INVARM). USAGE The INVARM board allows developers to interface a host PC with most of InvenSenses sensor products (mounted to a Universal Evaluation Board UEVB or Small Form Factor SFF board), and transfer serial data using the I2C and SPI protocols via USB interface. Additionally, there are some GPIO pins which may be used for general purpose signaling.
