This sub is being built so that a great white shark area can be explored. It will probably only last an hour underwater but the video should be stunning!

Sounds fantastic - hopefully we get to see some of the footage here!

The lighst are custom and controlled with a Teensy which is expecting a standard digital servo PWM range and frequency of 200hz. Same with the gripper.

Ahh ok, makes sense.

@jwalser

The main outputs pwm frequency can be changed with RC_SPEED parameter, but aux channels are always 50 Hz.

I don’t expect things have changed since that comment was made a couple of years ago, but I’m also not certain whether the SERVO_RATE parameter potentially applies to the AUX outputs. If not you may need to change the frequency your teensy code is expecting.
