Data logger that is pre-programmed to automatically record data from IMU, GPS, serial data and various pressure, humidity and distance sensors. OpenLog Artemis automatically detects, configures and registers Qwiic sensors. After the module is turned on, all incoming serial data is automatically saved in the file with the baud rate up to 921600bps. OpenLog Artemis also allows analog data logging via four ADC inputs. Voltages up to 2 V can be recorded with 14-bit precision, up to 1900 Hz for one channel and 1000 Hz for all four channels. Additionally, thanks to the built-in clock, all data can be marked with the login time.

The OpenLog Artemis module is based on the Apollo3 microcontroller from Cortex-M4F. The board also has a 9-axis IMU ICM-20948. The data is logged on a microSD card inserted directly into the slot located on the board. The module is also equipped with a socket and a LiPo battery charger. The recorder software is being modified and improved. Updating the system software is easy via the dedicated GUI Artemis Firmware Upload application.

The list of supported modules can be found on the product's website.
