Multiple serial communication
Is there a possibility to use another device at the same time, which is connected via USB port and using serial communication (24/7)? Also, after cutting off the current, does the device charge RPi until the battery dies or in case of having current again, does it automatically switch back to 230V?
Jan Toman
  • Serial communication with the PIco is only used when updating the firmware. You can use a Serial to USB converter as well.

    You can set the PIco up in 2 ways to handle mains power loss.

    1. PIco will run Pi on battery, until battery is low, then will shutdown Pi
    2. PIco will run Pi on battery, for a user specified amount of time, then shutdown Pi

    If mains power is restored, Pi will be powered from mains again.

How to add external 12v supply to UPS Pico?
Id like to install this in an auto and supply it with 12v from the cars battery. where would that connect to the UPS pico? do I need the terminal board? if so would it connect to the A/D 15v terminal?
David Madej
  • If you take a look at the WiKi - https://github.com/modmypi/PiModules/wiki/UPS-PIco-HV3.0-A-Stack-450-Plus - You'll see a picture of the PIco with some terminal blocks (bottom right, next to the buttons). There is a 2 pin terminal block, and a 3 pin terminal block.

    You'll want to hook up your 12v to the two pin terminal. The left pin is positive, and the right pin is negative.

What is the Auxiliary power that is mentioned.
Is there an additional 5V that can be drawn form the UPS aside form powering RPi
Jobin
  • Yes, there is a 5V @ 750mA output from the PIco that is backed up by the battery. The terminal block is required to use this - https://github.com/modmypi/PiModules/wiki/UPS-PIco-Terminal-Block

Can the pico cut power completely to the Pi board?
When the Pi is switched off, does the pico fully cut out power? I was hoping to avoid the situation where USB ports and HATs still pull power when the Pi is off
Russell Newman
  • No, this isn't possible.

Integrated Buzzer
Hi is the integrated buzzer accessible for control by an application running on the RPi or is purely for use by the PIco? I would like to use it to as an audible alarm with a specific pattern to notify the user that the wifi connection has been lost
Riaan Vermeulen
  • Yes, the buzzer on the PIco is programmable. Both frequency and duration can be set. Please see the program registers on how to do this - https://www.modmypi.com/download/pimodules/_28_03_2017-register-list.pdf - The buzzer is called a "sounder" in the documentation

Can the UR S5 button be pressed via software command via i2c for remote complete shutdown?
Sorry to bug you further but can you please tell me if there is any software commands that will perform this same hard shutdown remotely via the i2c capabilities of the UPS, or essentially if the Pi is locked up one must physically attend to the unit and hard reset. If there is an inbuilt watchdog timer on the ups which can force reset the pi if it locks up that would be great too.
Brendan Daniels
  • The PIco does have a watchdog that monitors a pulse train from the Pi. If the Pi hangs and this pulse train stops the PIco will restart the Pi. This can only be done if you have the gold reset pin installed though. We have a customer trying to access the UPS PIco from a microcontroller over I2C to do exactly this, shutdown the Pi from a different device - https://forum.modmypi.com/technical-support/hv3-0a-software-filesafeshutdown-not-working-correctly-t1902.html - However there does seem to be a bit of an issue (not sure if its the PIco or their setup yet)

Can the UPS Pico-Plus + RPi be reset externally with just unplugging the usb micro power cable?
Is there a possibility to hard reset the RPi and UPS Pico externally when it's unresponsive by just unplugging the pi usb power cable or do I always have to press the UPS Pico shutdown S5 button to full remove power from the RPi and Pico?
Brendan Daniels
  • Simply removing the USB power supply from the Pi whilst the PIco is attached will not reset the Pi, as the PIco will keep the Pi powered via battery. You need to remove power and press the UR button (S5) to reset the PIco in order for the Pi to be hard shutdown.

Recommended power supply?
Hi, With Pico UPS is RPi powered via USB port as normal, or does UPS pack take supply? Which power supplies are recommended? Thanks
Michael
  • The Pi is powered via the micro-usb power port as usual.

    If you are using the PIco **PLUS** version then you can power the Pi through the PIco using an external power source.

Raspberry Pi Power Supply - For MagicMirror
Hi, First of all I must say what a great website you have, it's so easy to use and find everything you need. Well I've purchased my first ever Raspberry Pi 3 and I'm looking at creating the MagicMirror2. I would like to run my Raspberry off of and additional power source in stead of the Raspberry Pi Official Universal Power Supply - 5.1V 2.5A (Black). Would this product do the job? I just want to have the least amount of leads coming from the MagicMirror as possiable. Many thanks in advance for all your help. If you could advise me what UPS PIci you would advise if this would be suitable. I'm a complete beginner so any help would be, gratefully appreciated.
Ian
  • The purpose of this product is to run the Pi off of a battery for a short amount of time (enough time to safely shutdown the pi) when the mains power is lost. It's not really designed to simply run the Pi indefinitely off of a battery. With that said, we do have large capacity batteries that will run the Pi for serveral hours. So yes, you could potentially use this.

    You will still need a power cable going to the Pi though to charge the battery when it gets low so I'm not sure how this reduces the amount of cables being used?
