What’s Special About the BlueSwimmer II Main PCB?
It is the brains behind the programming and behaviour of the device.
The main PCB is powered from the on-board lithium battery.
It controls the harmonics of the back-and-forth movement of the device.
It also interprets feedback from the various sensors in the device.
If the device does not start, and no lights are visible when it is turned on, then it is possible that the main PCB need replacement.
