Overview

The DK-20789 is a comprehensive development platform for the ICM-20789, an integrated 7-axis motion sensor that combines a 3-axis accelerometer, a 3-axis gyroscope, and a barometric pressure sensor. The board features an on-board Microchip G55 MCU with a Cortex-M4 core and 512KB of Flash, allowing for local sensor fusion and data processing. It serves as a complete evaluation system with an integrated debugger, enabling developers to prototype motion-sensing and altitude-tracking applications without additional hardware.

Why Choose This Part

This kit streamlines development by integrating the sensor, a high-performance 120MHz Cortex-M4 microcontroller, and an embedded debugger on a single board. The ICM-20789 sensor provides a wide range of user-programmable full-scale ranges for the accelerometer (up to +/-16g) and gyroscope (up to +/-2000dps), making it adaptable to diverse dynamic environments.

Applications

Drone Altitude Hold
Utilizing the integrated pressure sensor and 6-axis IMU for stable hover and precise vertical positioning.
Wearable Activity Tracking
Monitoring movement patterns and elevation changes using the low-power accelerometer and barometer.
Industrial IoT Monitoring
Detecting orientation changes and pressure fluctuations in industrial equipment or environmental monitoring systems.

Getting Started

To begin development, connect the board via USB to power the system and access the on-board debugger. Utilize the provided Sensor Fusion libraries and calibration tools to interface with the G55 MCU via I2C or SPI. Developers can use standard ARM-based IDEs to compile and flash firmware to the 512KB of available Flash memory.
