    Hello Everyone;

    I want to add 3 devices to my arduino uno and I wanted to know how I can add it to the arduino to use the GPIO for data transfer.
    Here is what I am thinking about:
    1 gps module
    1 magnetometer/compass
    1 wifi transmitter

    The idea is to connect all of those to my arduino and be able to send the gps and compass data through to the wifi transmitter to a wifi server(have already built/programmed it) that will be listening and logging the data.


    Does anyone have some pointers where i should begin?


    I was thinking about using some prebuilt modules, but everything i found uses rs232 and there is only 1 uart on the UNO and I am trying to stay away from the bit-bangin(software serial lib). However, as I said before, any help will be appreciated.

    The mega has three... I'm pretty sure you can get all three in SPI format... The Arduino has a hardware SPI module

    Hello Ian Rogers;

    I did consider the mega; however, I have a size constraint. The uno is already pushing it; i planned to PCB a clone(just to reduce the footprint) of the uno to fit my purpose.


    Thank you for your input.
