Does this do the same thing as an LTC2954 + MOSFET? Basically:mausberry wrote:You plug your original Pi power supply (male micro USB) into the switch. Then use a standard USB->micro-USB from the switch to the Pi's power port.
The GPIO pins are only used for communication, not powering the Pi. One lead sends a signal to the Pi and the other lead receives a signal from the Pi.
I'll post some more detailed photos of the switch. The leads to the board as well as the type of switch can all be lengthened/shortened/customized as necessary
This is similar, yes! Since the original posting I've actually redisgned the switch and replaced the relay with a MOSFET so that the board can be much thinner. Thew new PCBs are printing now and should be ready in a week, I'll post photos when they are done!Bakul Shah wrote: Does this do the same thing as an LTC2954 + MOSFET? Basically:
- when the RPi is powered off, push button briefly to turn it on.
- when on:
- push button briefly to signal the RPi. When it is ready to shutdown, it sends a signal to the switch to turn power off.
- push button for N seconds to force power off.
- very low standby power.
That could corrupt your SD data, so don't do that. You should allways shut it down with safety.rustek wrote:If I physically remove power from the switch at the mains adaptor and then replace the power, what effect will this have on the Pi if any?
