Hi all,
Looks like we have a requirement for a software controllable relay to physically press a reset switch on a board. I've been doing some hunting but so far have come up with nothing that looks likely.
Requirements:
Dimensions: At present unknown until we have a physical board in our hands Mountable: It must be something we can attach to the shelf next to the board Controllable: Must have some sort of standard interface for operation. USB would be a preference, but at a push we could use another board's GPIO pins.
Anyone know of such a product?
Thanks
Dave

Does it _have_ to physically press the switch? Can we snip out the switch and wire a relay across instead? You can get usb-controlled relays.

I'm sure Andy Green could build one in half a day...

Andy G? Any ideas?

Hi -
The lava lmp board "lsgpio" - level shifted gpio - is designed for that, plus provides 15 other wires you can "press other buttons" with or sense LED states etc.
You don't need a relay channel for it. The software interface is documented in the spec pdf from the wiki, it's ttyACM and ascii chars as usual.
Unfortunately I am just out the door to Korea for a week, I can send you one when I get back.
