All STorM32 boards have two LEDs, a green and a red LED, which provide information about the controller's current status. Some boards may have additional LEDs.
Red LED
The red LED is the heartbeat (health) indicator. Normally, it should blink at a frequency of 1 Hz.
In case of an error condition, such as a low battery voltage or a missing IMU, it blinks however much faster in order to signal the error condition.
Comment: When diagnosing an issue, inspecting the red LED's blink pattern can yield important information.
Green LED
The green LED indicates the current state of the controller.
Specifically, at startup it undergoes a sequence of ever faster blink sequences. When the NORMAL state is reached the green LED goes permanently on. For more details see Getting Started: First Startup.
Additional LEDs
Some boards may have additional LEDs.
