I have a Fingerprint Scanner - TTL (GT-511C3)
and I want to connect that with Raspberry Pi 2 Model B, through GPIO. I have referred this website, to understand what input will go for different pins on that scanner, and referred this to understand how GPIO works in Raspberry. Below image will have a connector and 4 individual pins to connect my PI on Pins [1, 17, 9 and 2]. Now, my doubt should I directly connect those black female connector to Pi GPIO male connector, or do I need a bread board to do that.
This is the only device I'll be connecting to my Pi.
P.S. I don't have much of a hold in electronics, so I just want to be sure. + I asked the same question on electronics.stackexchange, but got 0 fruitful response.
I have even looked here, as it is something similar to my case, but the approved answer is saying to connect the device on 14 and 15 pin, which I'm not sure, as it will provide ground and IO, but no power.
