I'm working on a project where I want to be able to use the SPI bus and I2C to send data to 2 other boards, I've seen some people say that SPI is for communication on the same PCB then others say you can with long wires and need boosters. Now this as caused a bit of confusion.
So the 10way ribbon cable should be no more the 150mm away from the main board, Would this cause inference with the SPI orI2C signals ?
And is there any precautions I need to take ?
I've attached a picture just to show I intend on doing it if possible.
