Counterfeit Joy-Con 2 Contains Rotary Motor, No Mouse Sensor

Counterfeit Joy-Con 2 has been a thing since last year, but I just saw its innards for the first time. The board and components actually look decent enough. Having a rotary motor (instead of a linear actuator for HD Rumble) but no mouse sensor is a dead giveaway though.
