This means that it just requires one data line (and GND) to communicate with the Arduino

DC-DC Adjustable Step-up Power Converter Module- XL6009 Decoder and TTL level output)Introduction : DC DC Adjustable Step up Power Converter Module is an adjustable DC DC step up module that accepts 5~32V DC input and outputs 5~48V DC, with maximum 4A current. It has very strong output ability and could output up to 4A current. It cannot be used to lower the voltage (the output voltage is always higher than the input). Pinout: IN+ input positive. IN input negative. OUT+ output positive. OUT output negative . Features : Module
