I am new to this but from my initial project requirements, I will need to join GPS Module and RFID Module to a Raspberry Pi 4. Do the GPIO pins support the required output? Is there any guide on how to join two modules to Raspberry Pi?
1Ah, nothing is impossible for Rpi. You might like to search "NEO^M", "NEO8M" and "RC522" this Rpi SE or EE SE forum for more details.– tlfong01Aug 29, 2020 at 7:51
1If you add "tlfong01" to your search, the newest results should be these:(1) raspberrypi.stackexchange.com/questions/116298/…, (2) raspberrypi.stackexchange.com/questions/113544/…. From these newest post, you can find tons of references to realize your innovative ideas. Have a nice project. Cheers.– tlfong01Aug 29, 2020 at 7:56
Short answer YES.
The GPS module uses Serial = Yes you can do that with a Raspberry Pi
The RFID module uses SPI = Yes you can do that with a Raspberry Pi
And for the question about "How", there are a ton of tutorials on this topics that are easy to find.
