Description

The Discovery-M1 helps to discover the INEMO-

M1 performance features and to facilitate its

evaluation. The INEMO-M1 is the smallest 9-axis

system-on-board (SoB) of the iNEMO module

family; it integrates multiple ST sensors with a

powerful computational core: a 6-axis

geomagnetic module, a 3-axis gyroscope and an

ARM Cortex™ M3 32-bit MCU.

The Discovery-M1 based on the INEMO-M1, and

including a pressure sensor LPS331AP,

represents a complete 10-DoF open platform able

to provide fast inertial application development

using MEMS sensors and the STM32. The pinout

of the two connectors gives a complete set of

communication interfaces in a very small size,

making the Discovery-M1 a flexible solution for

effortless orientation estimation embedded

applications.

To aid in user development and analysis, the

Discovery-M1 demonstration kit includes a PC

GUI for sensor output display and a firmware

Data brief

library to quickly support the use of the

demonstration board features.
