The Whadda Logic Level Shifter module provides 8 logic conversion channels to enable microcontrollers, sensors, and modules with different logic level voltages to communicate with each other. Each channel is fully bi-directional and is compatible with both Open-Drain and Push-Pull Logic drivers. The module can be used to convert 3.3 V to 5 V, 1.8-3.3. V and other common logical levels. It is recommended to pull the output actuation pin high with a pullup resistor to ensure that the outputs are properly actuated. If the different logic level data lines need to be isolated, the output activation line can be drawn low. This will put all I/O channels in a high impedance state.
