The Remora is a UI board which will connect to the Shark Converter Board. It will allow multi-levels of brightness with the Shark. The Remora UI will probably be simplified to three levels and latching (remembering last state)
All Remoras have been reprogrammed for 3 levels. No more SOS flash.
Remora: Low, Medium, High
The Shark is the Boost converter that can drive multiple LEDs in series.
**Add wires to Remora Option below**
See picture below for wiring the Remora up to a Shark board.
The Shark board must have the trim pot removed and the upper two pads shorted together. See picture below of the modified Shark.
The UI can be toggled by cycling power to the converter board when it's first powered up. Once the light has been on for more than a few seconds the UI is locked out and if the light is in a new state the new state is stored as the default.
You must turn the light off and wait for the capacitors on the Remora to fully discharge (~5 seconds) before turning on the light to cycle through the UI.
The Remora board covers the LED+, LED- holes on the Shark board. You should pre-wire the LED+, LED- wires if you need them to exit from the topside before installing the Remora board onto the Shark board.
The Remora board does not have to sit directly on top of the Shark. The two boards can be mounted side by side and wired up accordingly. keep in mind the length of the interconnect wires should be kept to a minimum.
There are three total connections, the wire as shown in the diagram and the two holes that mate with the Shark board.
Remove the trim pot.
Jumper the two top pads of the Shark Trim pot.
Add your LED +/- wires to the Shark board.
Add two terminal posts or stiff wires in the holes near the trim pot.
Align the two holes on the Remora to the two stiff posts on the Shark.
Solder the two posts to the Remora.
Solder the third wire to the Remora.
Hook up the LED wires and power input connections.
NOTE: All Remora UIs purchased after June 30, 2009 have been re-programmed for 3-levels only, no SOS.
