SparkFun SPX-15846 OpenLog Artemis

SparkFun SPX-15846 OpenLog Artemis (OLA) is an open-source data logger preprogrammed to automatically detect, configure, and log Qwiic sensors. This OpenLoog Artemis includes the ICM-20948 SPI interface and USB C with CH340E. The SPX-15846 OLA supports serial logging up to 921600bps and 9-axis IMU logging up to 250Hz. This OpenLog Artemis features 2-pin JST with LiPo charging, Qwiic connector with power control, optional external power switch, and SWD port. The SPX-15846 OLA operates at 20μA run current and 240uA sleep current. This OpenLog Artemis has a microSD socket supporting FAT32 and exFAT up to 512GB with power control and RTC 1mAhr battery backup.
