4 Channel Logic Level Converter 3.3V 5V TTL Module

The level converter is easy to use.

When the MCU and a 3.3 V device module is connected, the 5 V and 3.3 V TTL level mutual transfer is highly efficient.

The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using.

Near the RS232 character end is the RS232 level, close to the TTL character end TTL level.
