KY-051 Voltage Translator / Level Shifter KY-051 Voltage Translator / Level Shifter Picture Technical data / Short description 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 communicate. Nowadays since the most problems with signal noise/ signal disruptions has been cleared, the voltage range is beeing kept as low as possible to decrease the heat and decrease the energy consumption. Systems with 1.8V are not unusual these days. But to communicate between two different systems, like in our example (Arduino ----> Raspberry Pi), you have to shift the voltage range - if you don't, the systems with the lower voltage range will create more heat and could take constant damage. Pinout The Pinout is printed on the module board. T...
