- Module Size: Approx. 1.5cm X 1.5cm - Logic Level Converter, 3.3V 5V TTL level bidirectional transfers - When MCU and 3.3 V device module is connected , 5 V and 3.3 V TTL level mutual transfer is very convenient - Compatible with the bread plate, can be directly used and put on the bread board Instruction manual:
The level converter is very easy to use. The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. High voltage (5V for example) to the HV pin, low voltage (3.3V for example) to LV, and ground from the system to the GND pin. The two power share one negative power supply.
