Toughbox Nano - counts per wheel revolution?

We don't have a spare gearbox so I can't measure this now. What is the turns ratio between the wheel and the encoder? (assuming standard overall gear ratio of 12.75:1).

Or, stated another way, with the kit of parts encoder, how many counts per wheel revolution?

Isn't the encoder on the output shaft?

Re: Toughbox Nano - counts per wheel revolution?

From the KOP checklist:
  • The KOP output sprocket is 15-tooth
  • The wheel sprocket is 22-tooth
From the sensor manual:
Quote:
The encoders provided are 360 Codes per Revolution (CPR). With 4X quadrature decoding, you get 1,440 positions per revolution...
