Technical data / Short description
This level-shifter modulates the voltage of a digital signal into a higher or lower voltage. 4 channels are available which can be modulated.
There are many microcontroller-systems which are operating in different voltage ranges: older systems, like Arduino, are using 5V for their in/output pins and new systems, like Raspberry Pis, are using 3.3V. Back then, microcontrollers were needing higher voltages to municate. Nowadays since the most problems with signal noise/ signal disruptions has been cleared, the voltage range is beeing kept as low as possible to...
