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.

Hi all,

Looks like we have a requirement for a software controllable relay to
physically press a reset switch on a board.

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'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?

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

Andy G? Any ideas?

Thanks

Dave
