DF Robot DFR0913 Module is a logic level shifter and converter with a dimension of 47 x 87 x 39mm that operates on a 3.3VDC power supply and a 12VDC input voltage. It features a compact design and is manufactured out of premium grade components for superior performance and reliability. The logic level shifter and converter can convert a 12V input voltage into 3.3V logic level signals thus, bridging the interface between ‘low-power’ devices and ‘high-power’ ones. It is ideal for use in Arduino-based devices and various electronic applications.
