48 ANALOG INPUT + DISPLAY + DATALOG

Projects General Guidance
1

Hello guys,
I'm planning to build a setup that reads 48 voltages, and that displays it on the screen, and also generates a report in a form of csv.
Is it sufficient to have:

  • Arduino MEGA 2560
  • Adafruit 254 SD card shield
  • SparkFun DEV-11723 48 analog input MUX
  • SparkFun LCD-11741 touchscreen display
    I'm kinda lost and I don't know if I can connect all of this to just one Arduino MEGA.
    Thanks for help.

Why not?

7 pins for the analog mux, 4 for the SD card, two or three more for the LCD (I assume that's also on the SPI bus). That's about 10 digital and 3 analog.

Even an Uno or similar (Mini, Pro Micro) will connect all this just fine.
