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 http://cdn.sparkfun.com/datasheets/BreakoutBoards/Logic_Level_Converter.pdf 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! http://www.banggood.com/ESP8266-ESP-03-Remote-Serial-Port-WIFI-Transceiver-Wireless-Module-p-961244.html http://www.banggood.com/5Pcs-5V-1-Channel-HL-Trigger-Optocoupler-Relay-Module-For-Arduino-p-945176.html
