External PWM/DMX Inversion Adapter for Opal Drive
The PWM/DMX adapter allows external PWM-based LED dimmers and DMX PWM dimmers and control modules to interface with Opal Drive and Laser Wire™. Without using this adapter, Opal Drive will charge but not produce any light nor respond to PWM input.
This adapter must be used only at 5VDC across the PWM input and the DC Power input. Using at a voltage higher than 5VDC can damage Opal Drive and void warranty. The LED dimmer/adapter's PWM signal needs to be on the ground pin, and not on the positive voltage rail in order to receive signal properly.
*If attempting to interface Opal Drive with microprocessor platforms such as Arduino or Raspberry Pi, this adapter may not be necessary. Ground and PWM directly from the Opal Drive micro USB can be connected to the ground and PWM output of either microprocessor, as long as the peak voltage is 5VDC.
*Please note at this time that the PWM/DMX Inversion Adapter is in BETA mode, and does not have full linearity over the full range of 0-100% brightness.
