OpenLog
An open-source hardware data logger that records serial data to microSD cards up to 64GB.
What is OpenLog?
OpenLog is an open-source hardware data logger that captures serial data from devices like microcontrollers and saves it to a microSD card. It solves the problem of reliably recording sensor data, debug outputs, or any serial stream in embedded projects without needing a computer attached. The device supports cards up to 64GB and offers configurable baud rates and power-saving features.
Embedded systems engineers, hobbyists, and researchers who need to log serial data from microcontrollers, sensors, or other hardware in field deployments or prototyping.
Developers choose OpenLog for its simplicity, reliability, and open-source hardware design, which allows for customization and transparency. It provides a dedicated, low-power logging solution that works independently of a computer, unlike software-based serial monitors.
