Crowbits-Logic OR


The logic OR is a logic gate that creates an OR rule for your circuit. But unlike AND, the logic OR is a good option for projects where you want to detect two inputs but don't care which input is activated.



  • Single output port.
*Output indicator.


  • Operating Voltage: 3.3V DC
  • Supply mode: Crowbits Power Module
  • Dimensions: 56(L)*31(W)*13(H) mm


1)You also need a power module, such as Crowbits-Power Supply; An input module, such as Crowbits-Switch and Crowbits-Touch Sensor; An extension module, such as Crowbits-LED.

2)The connection mode is shown in the figure, but the signal feet of the input module and the output module must be connected.

3)Then, turn on the power. When you press the self-locking switch or press the Touch Sensor, the LED light.
