Note

This list is work in progress and I have not tested many of these controllers myself. A status for each should be added based on user feedback. I plan to add capabilities too: max number of axes, plugin support etc...

¹ A version with the programming header brought out is required, it is near the USB port and may or may not be soldered in.
