The rest of the time it's <100 mV when testing. If I remember right, from the doccy's, it's 100 hz. I may be off on that though, I'll have to look. AFAIK, the BlueESR is the only one available from flipper now, and I don't see a kit that has a single cable? I only see one model with two options - one as a kit, and one as assembled.
