2.1.2 LED Indicators
Starting with the upper left LED and moving clockwise, the indicators are
RNG, RXD Data, USB Data, and RPM.
During power-up initialization or after a system reset, the normal LED
pattern has both USB Data and RPM LEDs OFF while RNG and RXD
Data LEDs alternate being ON. The power-up initialization lasts for
about 5 seconds followed by all LEDs being on solid for about 1 second
then all turn OFF before beginning normal operation.
If a bootloader checksum error is detected during initialization, the RXD
Data LED turns ON alone and remains ON (not recoverable).
If a program checksum error is detected during initialization, the RPM
LED turns ON alone and remains ON (not recoverable).
