    • Status

  • The OpenLog Artemis automatically scans, detects, configures, and logs various Qwiic sensors plugged into the board (No soldering! No programming!). Currently, auto-detection is supported on the following Qwiic products:

    This OpenLog uses common microSD cards to record clear text, comma separated files. You probably already have a microSD card laying around but if you need any additional units see the related items below. The OpenLog Artemis supports microSD cards formatted as FAT32 as well as the older FAT16 formats up to 32GB. Currently, the OpenLog Artemis does not support microSD cards formatted with exFAT but we plan to offer support for it in the future

    Very low power logging is supported. OpenLog Artemis can be configured to take readings at 500 times a second, or as slow as 1 reading every 24 hours. You choose! When there is more than 2 seconds between readings OLA will automatically power down itself and the sensors on the bus resulting in a sleep current of approximately 18uA. This means a normal 2Ah battery will enable logging for more than 4,000 days! OpenLog Artemis has built-in LiPo charging set at 450mA/hr.

    New features are constantly being added so we’ve released an easy to use firmware upgrade tool. No need to install Arduino or a bunch of libraries, simply open the Artemis Firmware Upload GUI, load the latest OLA firmware, and add features to OpenLog Artemis as they come out!
