Spike Relays
 

How many are allowed this year? Is there a limit? So far our robot uses 7 of them, I'm just wanting to make sure this is legal.

Re: Spike Relays
 

As many as you want.

Re: Spike Relays
 

No more than 102 based on last years GDC ruling. See this post from the Q&A on how it was calculated.

Re: Spike Relays
 

The question then becomes:
How would you legally CONTROL more than 16 spike relays?

Re: Spike Relays
 

Added digital I/O and DSC. Invariably the answer to the question "Can we...?" is "how much do you want to spend?"

Re: Spike Relays
 

PWM Y cables up the number somewhat.

Of course they could just be structural members...

Re: Spike Relays
 

Would it be legal to split the forward and reverse out to different Spikes?

Re: Spike Relays
 

What are you trying to do?

Re: Spike Relays
 

I'm just curious how many spike relays can you legally (and presumably, independently) control on an FRC robot.

Don't worry. I do not have a wish or need to do so.

Re: Spike Relays
 

I was asking for additional data to answer your question above.

Re: Spike Relays
 

Oh, I'm sorry, I misunderstood.

On the Relay Outputs on the Digital Sidecar, the Forward and the Reverse are actually separate pins. Thus, the forward and reverse pins could be wired to separate Spike Relays, effectively doubling the number of independently controlled Spike Relays.
(I suppose they're not quite independent, seeing as only one can be on at a time)

Re: Spike Relays
 

I suppose you could. I have an IFI doc called IFI-spike-blue-guide that outlines the output states for individual inputs. It should still be available on the IFI website.
