Description
The DEV-16832 OpenLog Artemis is a Cortex-M4F based Apollo3 microcontroller log board. It is preprogrammed to automatically log IMU, GPS, serial data, and various pressure, humidity, and distance sensors. OpenLog Artemis, or "OLA," automatically detects, configures, and logs Qwiic sensors. The OLA is specifically designed for users who just need to capture a lot of data to a CSV and get back to their larger project. This OpenLog uses common microSD cards to record clear text, comma separated files.
