I actually came here looking on how I can get a capermit I'm working on out there. It doesn't have SSRs on it but rather exposes GPIO lines protected by a transistor. It will drive 3V3 and use 2-pin JST connectors. I built a prototype to run some appliances attached via a Powerswitch Tail II device but my profile is not pretty at all. I'm also exploring a wireless remote solution instead of the JST connectors but that's way down the road. if this idea is interesting let me know and I will see what I can do. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
