YROTATE-IT-RX111 Motor Control Kit
4. LEDs functions description
Some of the LEDs available on the board are directly connected to the hardware and allow the user to understand
the status of the board. Please refer to the LED map for the following indications:

DL4 is connected to the output of the 12V step-down DC-DC converter and indicates the presence of the
switches drive supply;

DL5 is connected to the output of the 5V step-down DC-DC converter and indicates the presence of the 5V
logic power supply; then a low drop-out linear converter produces the 3V3 logic power supply.
DL4
DL5
DL3
DL2
DL1
Other LEDs in the board are driven via software, in particular:

DL1 is the USB communication indicator and blinks when there are data exchanges between the PC and the
board.

DL2 is free for the user (in the default software it is on when the main interrupt is active).

DL3 is blinking slowly if the control section MCU (RX111) is running normally. In case of hardware or software
alarms, the LED DL3 is blinking quickly.
