Using C and not Python
For a new product using RPI3's we need to add a small backup unit to detect a power down, flag it and maintain the RPI for just a few minutes whilst we do and orderly shutdown. All of the project is in C and Python is not installed or used, I have a master loop and I just need need to read a flag or func() from this unit to tell me that it is the reserve power state and I can do the rest. I cannot find any software details apart from installing a Python section, which would not be applicable to us. Are there any full and complete instructions for me to work out what to do, eg is a GPIO line pulled low on reserve power, because if so, I could write the func.

  • The PIco requires a python script to be installed to function properly. If you don't want to use python then you will need to port the python code to C -

    We will not be able to provide support for the product if the manufacture's scripts aren't used.

The 12v terminal block is listed as optional, but there isn't anywhere to order the option in checkout?
Why not just include the 12v terminal board as a standard for the pico? I'd like to order a Pico + with the 12v terminals attached. My soldering skills, well, suck xD I have a 12v monitor my pi is attached to, so I was thinking of putting a splitter, running 12v to the Pico and 12v to the monitor, using a 12v 5A source.
  • I may have been mistaken. I was referring to the two green terminals shown on the first image of the Pico hat. Is it possible to have those soldered on before delivery?

  • The terminal block add-on isn't something we currently stock. (It also doesn't allow you to power the PIco with a 12v source, it offers a level shiffted 12v serial inteface to the Pi)

    If you want to power your PIco with 12v, then you just need to solder the green terminal blocks, as seen in the product picture. This then allows you to power you PIco from a 7 - 28V source.

Upper voltage limit - capable of 28.8V?
The UPS Pico Advanced has its upper voltage limit listed as 28V, however I would like to supply it from a pair of 12V lead-acid batteries meaning the actual voltage could reach ~28.8V. Would the board be capable of this?
  • No. The maximum is as stated, 28V.

Support for Rapsberry pi zero W
Is Pico UPS supported for Rapsberry pi zero W? Can it be installed besides pi zero to have minimal device thickness? Does it has alarm notification for low battery ? Need qty- 200 , with LiPO 4000mAH.
Prashant Rai
  • Yes this is compatible with the Pi Zero W. If you want to use the RUN pogo pin (used for restarting the Pi if it crashes and after power resumes) then no, you will need to mount the PIco on top of the Zero.

RTC issues
is anyone else having issues with the PICO UPS and real time clock usage. It was working fine for a while and now I'm receiving "read errors" when viewing dmesg. And when attempting "sudo hwclock -r", I get an error stating "ioctl(RTC_RD_TIME) to /dev/rtc to read the time failed: Remote I/) error". Any ideas?

Can Advanced version function as true UPS?
My Raspberry Pi based robot runs carries 7.2v 5000mAh NiMH based power, and has a 5v switching power supply for the RPi needs. Could I run the 7.2v into the UPS PIco Advanced 7-28v input and have it power the RPi continuously as a true UPS (eliminating the 5v switching PS)?
  • Yes, I don't see why not. The PIco will regulate the power from the external source to 5V to power the Pi, and additionally act as a UPS between the battery & Pi

Where can I get HV3.0B+ user guide?
So far the only user guide available (145 pages) is for HV3.0 ( Github wiki page does not provide the "155 page guide" that ModeMyPi LTD referenced in their reply to Nick in this FAQ.
Operating system and software installation
I saw, in the instructions, that it goes over installing the daemon and all other software that runs the Pico, utilizing Rasbian as the OS. Would I follow the same procedure if Raspbian is not the OS installed? Say, for my example, you have berry boot bootloader installed which then loads RetroPie. Would I just load up RetroPie, press F4 to enter the console, and proceed from there?
  • Yes, but please note, the software has been designed to work with Rasbian, and has not been tested on other OSs.

Shutting down completely
Is there a way to programmatically (or via a service) shutdown the Pi completely where restarting it is accomplished by plugging power back into the Pi's micro USB (just like its started when there isn't a UPS HAT)?
Karl Siegert
  • If there is no mains power to the Pi, the PIco can shutdown the Pi, and completly remove power. When mains power is restored the Pi will power back up by itself.

    If there is mains power, then the only way to truely disconnect the power is by turning off the mains.

Actual installation guide exists?
Do you ever plan on putting together an actual installation instruction guide? The one on the wiki is laughably inadequate. It doesn't tell you what gets soldered where, or how to program the programmable buttons. You have also neglected to include any installation or documentation on the HV3.0B Plus. The amount of actual documentation, provided by the creator of the UPS Pico hat, is really sad.
If I intend to power my Pico with 12v, is the Bi Stable Relay required?
I'm not exactly sure what the bi-stable relay is, for one. But if I intend to power my pico, say with a 12v 5A power supply, would I need to attach the Bi-Stable relay device to the pcb? It would be nice if there were an extensive installation guide that covered not only where and how to attach the various components, but what exactly they are as well.
  • No, you don't need the bi-stable relay to power the PIco with an external 12V source. 

    You just need to solder the two pin terminal block, then wire up the + and - lines of your power source to the terminal block. - If you scroll down to the second picture, you can see (bottom right of the PIco) the terminal blocks that are labelled "+" and "GN". These are the two you need.

Can the Pico + power both Pi3B+ and the Raspberry Pi 7
Using a 12v power source wired to the Pico, can it provide both power to the Raspberry Pi 7+ touchscreen and to a connected Raspberry Pi 3 B+? And would a beefier 4000mAh battery be recommended for such a setup, in the event of power interruption?
  • The PIco can supply 5v @ 3A to the Pi, which is more than enough to power the touch screen as well, which uses aprox. 400mA

    A larger battery, as you mentioned, would also be recommended.

Update! HV3.0B+ now fully compatible with the Raspberry Pi 3 Model B+ (and all previous revisions!) 

UPS PIco HV3.0B+ Stack 450 Advanced is an advanced uninterruptible power supply for the Raspberry Pi A+/B+/2/3, that adds a wealth of innovative power back-up functionality and development features to the innovative microcomputer! The UPS PIco will automatically shut-down your Raspberry Pi if there is a power failure, and can be set to automatically monitor and reboot your Pi once power has been restored!

The UPS PIco HV3.0B+ Stack 450 Advanced features a 5V 3A output, designed for use on the latest Raspberry Pi 3B+, and has the gold reset pin in the correct place!! If you're looking for a fully enclosed solution, we've designed a nifty UPS PIco case!

In addition to all the features contained in the standard UPS PIco, the UPS PIco HV3.0B+ Stack Advanced features the following:

  • Extended Voltage Input 7 - 28V DC - Protected with Zero Voltage Drop Inverse Polarity Protection, PPTC Over-current, and ESD. Ideal for Cars, Trucks, Buses and any industrial high voltage applications.
  • Dynamic Power Tracking (DPT) - Charges the battery according to available input power from 100 mA - 1200 mA. DPT checks the input current every second, and adjusts the charging current based on this value making it ideal for Solar Panel applications.
  • Bi Stable (Zero Power) Relay - With dual separated independent contacts
  • Optical Isolated Input (Opto-Coupler) – Readable as A/D values

The UPS PIco is equipped with a 450mAh LiPO battery specially designed to enable safe shutdown during a power cut.
