OpenLog UART MicroSD Data Logger Module

Record a compatible device's UART output to a memory card with an OpenLog serial data-logger module.

✅ Keep serial data for later review - The recorder saves the host's serial output as text on a suitable card.

✅ Match the host's data speed - Configurable baud-rate settings let you align the recorder with the sending device.

✅ Change settings through the card - A configuration file provides the described way to adjust serial settings.

Keep a record while the device runs

A circuit can send useful status or test data while it operates. A serial logger provides a local record that can be examined later, without requiring a computer to remain attached throughout the test.

Match the baud rate, signal levels and data format before recording. Use a suitable formatted microSD card and verify that the log is being written; flight-control use also depends on compatible firmware and its configuration.
