FAQ

Question:How does this module work?

 Answer:

Conversion level range: 1.8V-6V, as long as not more than this range, can achieve mutual conversion.

Here is an example of 3.3V, and 5V interconversion.

VCCA/VA input 3.3V power supply.

VCCB/VB input 5V power supply.

GND is connected to the negative side of the power supply, and the two power supplies share a common ground.

Ax input 3.3V TTL level, Bx will output 5V TTL level.

Bx input 5V TTL level, Ax will output 3.3V TTL level.

Question:Can this module be powered externally?

The module is used for level conversion, not for power supply, VCCA/VA and VCCB/VB are required for input voltage, but not for external output voltage.
