Any digital encoder, either linear or shaft, should work. Especially, those
with TTL outputs and 5 V supply voltage would be the best fit. You want
a reasonable resolution, somewhere between 2000 counts/inch as an
absolute minimum, and 20000 counts/inch max. If you have too high
a resolution encoder, the CPU will be overloaded cranking out step
pulses, and even a small following error will overrun the 128 count
maximum following error on the Gecko, and it will fault.
