Logic level shifter features four bi-directional channels, allowing for safe and easy communication between devices operating at different logic levels.
Enables interaction between different logic levels in the same system e.g. send 5V logic signals to 3.3V tolerant inputs. For example: connecting an Arduino (5V device) to an ESP8266 (3.3V device).
Signals can pass in both directions.
Supplied with 2 header strips for easy connection to breadboard.
Note that the ground connections need not be used if the 3.3V and 5V grounds are tied at another point in the circuit.
