LED (OVL)

The LED with the “OVL” marking shows a thermal overload of the NEXTuino.

At the NEXTuino RISE there are 2 temperature sensors integrated. They are placed on the Relays-Board and on the Control-Board. If the temperature goes over 80°C the red “OVL” LED will turn on and indicate a thermal overload.

At the NEXTuino PEAK it is the same but the overload signal will also be available at the microcontroller PE7 (Arduino Pin 9). Therefore, you can use this signal in your user program.

At the NEXTuino CREST, additional to the thermal control, the “Half-Bridge” Driver also has a FAULT signal which is also connected to the NEXTuino general overload signal. Internal protection functions are provided for undervoltage, charge pump faults, overcurrent, short circuits, and overtemperature.
