using serial/uart to connect a CO2 sensor
#1
Hi,
after successfully soldering and connecting the full PCB kit to my Raspberry Pi 3 I want to add a CO2 sensor using this tutorial https://www.circuits.dk/testing-mh-z19-n...or-module/. As far as I can tell the data pins 8 and 10 which are used for connecting are not used by the PCB kit. Is this correct? And is it possible to simply reuse the power from pin 2 and the ground from pin 6 or should I connect to different pins?

Please bear with me if those are stupid questions. It is my first home automation / electronics project.
