I got the servo(attached),
it has shaft encoder, but I don't
think it has quadrature output
as it has only 3 wires, it's optical tho.
I'm thinking maybe the photosensor
can do quadrature but the circuit board
is design only to read RPM, maybe I
could modify the board to make it
quadrature? any idea if it's possible?
It's a JapanServo type DS48BE25,
can't find info of it.
TIA
