Re: small superbright green LED panels?
get a Spike relay, and use it to switch power on or off, if that's what you are trying to do.

Re: small superbright green LED panels?
The RIO won't be able to provide enough current to drive one of these directly. If you want the ability to turn the LED on and off, you'll need to use a relay module. The only legal one is the Spike. IF you're not worried about that current draw, you can just plug them straight into the PDP.

Because the driver is a constant current source, you can provide power to it directly from the PDB, there is no need to use a VRM to power it. The connection to the RoboRIo is as simple as connecting the "CTRL" (D+), these are the dimmer inputs, input on the LED Driver to a digital out on the RoboRio. There is no need to connect the "DGND"(D-) as GND is provided by the power GND. Setting the digital output low turns the LED off, and high turns it on. EASY PEAZY! |

Re: small superbright green LED panels?
Spikes are no longer sold - so long as you are not using it to control motors or other actuators, you can get an off the shelf relay for controlling any sort of lights on your bot.

Re: small superbright green LED panels?
Thanks for the update on Spikes...we have been using them for a long time, and have plenty, so I wasn't aware that you can't buy them.
Also interesting about the power supply, that makes life easy |

Re: small superbright green LED panels?
Depending on the current draw, you may be able to use the PCM to power these. I'd have to verify the legality of that for a competition robot thought. I believe the PCM can source around .6 amps for relays.
