{"title":"SparkFun OpenLog Artemis (without IMU)","handle":"sparkfun-openlog-artemis-without-imu","url":"/products/sparkfun-openlog-artemis-without-imu","description":"The SparkFun OpenLog Artemis (OLA) is an open-source data logger built on the Artemis module (Cortex-M4F Apollo3 microcontroller). It comes pre-programmed to automatically detect, configure, and log data from Qwiic-enabled sensors — no coding required. Simply plug in a compatible sensor, power up, and data is recorded to a microSD card in CSV format.\n\nThe OLA supports serial logging at up to 500,000 bps, four 14-bit ADC channels (up to 1,900 Hz single-channel), and an onboard RTC for timestamping. Ultra-low-power sleep modes draw as little as 18 µA, enabling months of battery-powered logging from a standard LiPo cell with built-in 450 mA charging.\n\nKey Features\n\n\nAuto-Detection – Automatically scans and configures connected Qwiic sensors\n\nNo Programming Required – Pre-loaded firmware handles detection, configuration, and logging\n\nUltra-Low Power – 18 µA deep sleep; automatically powers down between readings longer than 2 seconds\n\nConfigurable Rates – From 500 readings/second to 1 reading every 24 hours\n\nUSB-C Interface – Configure via serial terminal at 115,200 bps; data streams to both terminal and microSD\n\nBuilt-in LiPo Charging – MCP73831 charger at 450 mA with battery connector\n\n4 ADC Channels – 14-bit precision, 0–2 V input (3.3 V tolerant)\n\nRTC with Battery Backup – Timestamp all logged data\n\nEasy Firmware Updates – Use the Artemis Firmware Upload GUI, no Arduino IDE required\n\n\nCompatible Sensors (Auto-Detected)\n\nuBlox GNSS modules (ZED-F9P, NEO-M8P-2, SAM-M8Q, ZOE-M8Q, NEO-M9N)\nEnvironmental: BME280, MS5637, MS8607, LPS25HB, SCD30, CCS811, SGP30, SGP40, SN-GCJA5\nTemperature/Humidity: TMP117, AHT20, SHTC3, MCP9600\nPressure: MS5837, SDP31, MPR0025PA\nProximity/Distance: VCNL4040, VL53L1X, VEML6075\nOther: NAU7802 (load cell), MAX30101 (pulse oximeter), ADS122C04 (PT100 ADC), Qwiic Mux\n\n\nSpecifications\n\n\nProcessor: Artemis Module (Cortex-M4F Apollo3)\n\nPower Input: 3.3–6.5 V (VIN), 5 V (USB-C), 3.6–4.2 V (LiPo)\n\nCurrent: ~20 mA run / ~80 µA sleep / ~18 µA deep sleep\n\nSerial Logging: Up to 500,000 bps\n\nADC: 4 channels, 14-bit, up to 1,900 Hz\n\nStorage: microSD (FAT16, FAT32, exFAT up to 32 GB+)\n\nPorts: 1× USB-C, 1× Qwiic I2C, 1× LiPo JST, 1× SWD header\n\n\n\nNote: This version does not include the ICM-20948 IMU sensor. All other auto-detection and logging features remain fully functional.\n\n\nResources\n\nHookup Guide\nSchematic (PDF)\nEagle Files (ZIP)\nBoard Dimensions\nApollo3 Datasheet (PDF)\nArtemis Integration Guide (PDF)\nFirmware Upload GUI (GitHub)\nHardware Repo (GitHub)\nArduino Core (GitHub)\nCH340E USB Drivers\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2108,"title":"Default Title","sku":"SF-DEV-19426","price":96.1,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":1,"option1":"Default Title"}]}
