Voltagetranslator

1. GENERAL INFORMATION & SAFETY INSTRUCTIONS

Dear customer,

Thank you for choosing our product.

In the following, we will show you what to consider during commissioning

and use. If you experience any unexpected problems during use, you are

welcome to contact us.

This level shier converts digital signals from one voltage level to another.

There are 4 available channels that, can be converted.

At present, there are many microcontroller systems operating in dierent

voltage ranges: e.g. the inputs and outputs of older systems such as Arduino,

based on an Atmega controller, with 5V level, the newer Raspberry Pi com-

puters based on an ARM controller, with a voltage level of 3.3V.

This can be explained by the fact that higher voltages had to be used in the

communication between microcontrollers, because the input stages have a

higher distance between the voltage level for [Digital ON] = 5V and for [Digi-

tal OFF] due to noise / interference in the cables. = 0V have needed - In the

course of the modernization input / output stages of the controllers have

become signicantly better and you want to keep the voltage used as low as

possible today, so that heat generation and power consumption decrease.

So today the use of 1.8V systems is not uncommon.
