[SOLVED] how to connect Bluetooth module to arduino uno

I would like to know how to connect the Bluetooth module to arduino uno board. My Bluetooth module is this

I see no ports. do I need to buy a special cable or something?

Issue solved, please remove this thread, I cannot delete my own threads

Far better had you "shared" your solution.

Nothing important, I called my uncle, he fix electronic stuff, so he showed me where it should be placed

I should put the pins of the modules where it says tx, rx. But I saw other people connecting the module to arduino without using the pins, they used cables instead so I asked.
