Question:I know you can connect vcc to 5v but can you connect the other pins to 5v? (ex: with an arduino uno would i need a logic level converter?)
Answer:No the module is 3.3 V so you will need a logic level converter or 3.3 V Arduino like the pro mini. 5 V is supported because there is a 3.3 V regulator on the board.

Read the last sentence of the product page on the manufacturers website: http://www.hiletgo.com/ProductDetail/1953399.html
if you look at the schematic:
I don't know if the version you have has the voltage regulator but maybe attach 3.3V and then probe for voltage on the other side of the regulator
