    Nice logic level converters. Be aware, you need to power it with 5V AND 3,3 V. You got two channels. For each one there's a transmission pin and a reception pin.

    The inputs / outputs of the Arduino DUE can accept 3.3V only. If you want to connect the Arduino DUE to TTL technology circuits (5V), you must have these modules. WARNING: THE MODULE CAME WITH NON-WELDED PINS.

    The RX pins are unidirectional high to low. The TX pins are bidirectional high to low or low to high. This makes the board ideal for a variety of uses. See for svhematic diagram of the board.

    I used this level converter to control the 5v relay module with 3.3v wifi shield.. Works like a charm!
