Re: Looking into motion control/breakout boards and after recommendations
It depends. the 5i25 is a PCI card. The 6i25 is a PCIe card. Both take two daughter cards including the 7i76. So the one to choose depends on your PC hardware
The 7i76e basically rolls the 6i25 and the 7i76 into one single ethernet card. 5 stepgens, 32 inputs, 16 outputs, analog inputs, 2 MPG inputs, spindle control.
Once installed, there is no difference in performance between PCIe and ethernet.
I prefer the ethernet cards but if I was building a machine that had an integrated console, I might go the PCIe path. However when you can get tiny PC's like the Odroid h2+ or even a raspberry pi4 running linuxcnc, why bother with anything other than ethernet?
