Hi,
I want to know if this 3.2 inch LCD screen for MEGA 2560 R3 Board can work with rasberry pi zero. The link of the screen : https://www.aliexpress.com/store/pr...o-MEGA-2560-R3-Board/1630603_32761038971.html . It very cheap before I buy I want to make sure it compatible. thanks for help
It depends on your definition of "can work with." The Mega uses 5V power and logic levels. The raspberry pi uses 3.3V. Also, some of the pin assignments in the double row headers are different. If power and ground pins don't match up, you won't be able to simply plug the units together.

Now, if you don't need it to just plug together, you can run wires pin to pin to make all the correct connections, providing level shifting as needed. Then all that's left is writing code for the devices to communicate. That's almost certainly equally possible on either platform.
