Smoker

Taigen/Heng-Long smokers are direct plug-and-play into the SMOKER port on the TCB. Polarity is marked for custom projects, but doesn't matter for the Heng-Long and Taigen units. You do not need the special Heng-Long “proportional” smoker since the TCB takes care of the proportional movement, however the proportional unit can still be used.

For people wanting to create their own smokers, the SMOKER output supplies battery voltage at up to 3 Amps (the maximum current rating of the JST-XH connector, the MOSFET can actually handle more). PWM is unidirectional at 31kHz (ultrasonic).

You can also specify the smoker's idle speed, fast idle speed (speed with transmission disengaged), and max speed - see the Motors tab of OP Config for these settings.
