SparkFun ESP32 9-DoF Datalogger - Qwiic

The SparkFun ESP32 9DoF Datalogger - Qwiic makes sensor data collection effortless—no programming required. This compact, ready-to-use datalogger is designed to automatically detect, configure, and log data from Qwiic-enabled sensors, including IMUs, GPS modules, and environmental sensors like temperature, humidity, and pressure. It supports data output in CSV or JSON formats, saved directly to a microSD card or sent wirelessly via WiFi to cloud-based IoT services.



Built around the ESP32-WROOM-32E, this board features onboard 9DoF motion sensing using the ISM330DHCX accelerometer/gyro and MMC5983MA magnetometer, providing detailed motion tracking out of the box. Power it via USB-C, LiPo battery, or VIN, and access an easy-to-use serial menu for configuration. You can even update firmware over-the-air or via microSD—no software installation necessary. Whether you're logging at 26Hz or once every 24 hours, the system is optimized for low-power applications and remote deployments.
