Power Pi 4 or 5 from 12 volts

 

Our club is in the consideration mode for a Pi based packet system with expansion to a VHF an HF RMS. The site has a generator for backup but I know generator power can be dirty and not immediate. We have a 50 amp Astron and I would like to run the Pi from that. Not settled on the verson of Pi but both Pi4 and Pi 5 are in consideration.

So, what would be the recommendation or success stories with a hat based UPS in the pie and what is a good way to power it from the 12 volt Astron?

There was a huge mess of a thread yesterday for this?

pi4 you can easily power?
pi5 is more complicated depending if you directly power the rail?

I've had great luck with Waveshare UPS HATs as they:

?? - Offer top or bottom style HATs for different Raspberry Pi form factors
?? - Allow for simultaneous run and charging
?? - offer I2C monitoring of power status, load, etc.
?? - offer different battery types (21700, 18650s and Li-Ion packs)

?? Rpi4 Top: (uses the GPIO header)
?? Rpi4 Bottom: (uses pogo pins)

I *think* their 5A HAT board is compatible with the Rpi5 but that needs to be researched.?

The main issue I see here for you is their DC input is 8.4v on most of their units and not say 12v.? This is easily dealt with a good quality adjustable buck-boost unit such as (make sure the unit you buy can keep up the expected voltage at it's max load -- most DON'T).

If you are just running a basic packet system for site telemetry, digipeater, etc, you don't really need a ton of horsepower. An RPi3B+ is normally plenty adequate with a lot less power and cooling issues.

Update on my project. I have tried both of the following buck converters with good results. I’m only running a fan, USB-Serial, and a soundcard so I’m not loading it much.







The DROC meter should not be believed but its not far off. Both have operated on my bench from the same DC supply that is running my IC-7300 and I haven't noticed any noise.

I have also used them on a Pi 3 and the most significant factor is getting away from off-the-shelf micro USB cords and using cords intended for power.


?

So far no low voltage warnings on the Pi 3.

I have also added a Pi Power from Sunfounder and it seems to be working well. It has some suggested safe shutdown software so I am going to add that to the Pi.

?


Thanks for the suggestions.

Dave, does the DROK allow you to have it power-on with the USB port active? ?I bought some of these in the past where you have to go into a menu after turning on the power and then select the USB power output to be enabled. ?After turning off the main supply and turning it back on, the DROK reset (of course) but comes up with the USB output disabled. ?I had to go back into a menu to turn it back on. ?Is this still true??
?Thanks!

Tadd,

Not sure about the USB, but I'll give it try later today. I use a micro USB rated for 3 amps connected to the screw terminals for my Pi 3 to avoid low voltage alerts that I get with the USB-USB Micro cable. I know from my days working with a building automation Bacnet router that those cables are problimatic as power cables.

I'm a little slow to respond but this does look like a good product. At the time we were making a decision, the Pi 5 was still a little hard to get. It is certainly something I would consider today. We are about to add a VARA HF port to our BPQ node and putting that on a Pi 5 might be the way to go.

I've purchased a couple items recently. Although they supply 3A instead of 5A, I haven't found 5A necessary for the Raspberry Pi 4B. They work fine. The one wth the USB type C plug fits directly to the Raspberry Pi.

Although I've not used that particular product, I have been very favorably
impressed with the design and operation of several other GeekWorm products.

Mats,
Off topic:
My sons are asking me if you are the "Mats Sundin" who played ice hockey in the National Hockey League here in the U.S.?

On topic:??

I use several different 9-16 V to 5 V converters and USB A distribution blocks with USB A to USB "x" type cords often with 90 degree plugs to easily fit in small cramped spaces with bending cables.??

I tend to avoid using RPi shields for power alone, preferring to make the header available for other functions as needed.

The other benefit of this approach is that my backup power can all be 12-15 V with most of it consisting of LiFePo4 batteries between 12.8-14.6 V.? This greatly simplifies things.

Thanks!

I have used these to successfully power my RPi5 with NVMe SSD: ?
$13 ? YIPIN HEXHA 10-32V DC in to 5.2V 6A dual USB type C outputs ?
$10 Klnuoxj 8-32V to 5V. 5A. USB-C PD Step Down Converter. 95% effeciency, Waterproof.?
?
The RPi5 will run fine with 3A or more at 5V PD, if there is no USB load, but a 5 ampere or more 5.2 V supply is necessary to draw the maximum 1.6A from the USB ports.? ??
?
Normally, the RPi5 is configured to use USB-C Power Delivery (PD) protocol, to negotiate 5A from the PD capable Raspberry Pi 5.1 volt mains power adapter,?
and shuts down if it fails to get PD acknowledgement that 5 A is available.?
?
However, if you edit and add the following lines to the end of file /boot/firmware/config.txt :?
? usb_max_current_enable=1?
This will force the RPi5 to ignore the Power delivery communication, and assume the power supply is capable of delivering 5A.
This change allows many 12 volt to 5.2 volt USB power converters and automotive USB outlets to power the RPi5.?
?
The USB-C Power Delivery 3.0 standard specifies a 5 volts at 3.0 amperes; ?however, the PD protocol allows for requesting higher current. ?
The Raspberry Pi 5 wall wart acknowledges a PD request for 5 amperes.?
?
The RPi5 will deliver an "Under-voltage" warning when operating below 4.63 volts, as measured at GPIO pin 2 or 4.?
?In Raspian OS, a lightning bolt appears in the upper right corner of the display.
?In Raspberry Pi OS, a "Low voltage warning" text appears in the display upper right corner.?
?"Under-voltage detected!" is also logged in dmesg for each occurrence.?
?
Often the cause is too much voltage drop in a poor USB power cable.?
I have taken apart flimsy cables where the wires were not soldered, and relied upon the rubber over-molding to hold the wires in contact with the connector pins.??
USE A BEEFY USB CHARGING CABLE designed to charge smart phones and laptop fast charging:?
? $5 USB A to C ??
? $6 USB-C to C ??
?
To see what the RPi5 measures on the 5V input, enter on the terminal:?
? ?vcgencmd pmic_read_adc | grep EXT5V_V
You will be surprised at the voltage drop in most USB supply cables.?
?
With all USB loads attached, enter in the terminal:?
? dmesg | grep voltage?
To see if "Under-voltage" is occurring.?

Mats,
Thanks for the chuckle!? I shared it with my hockey-intense sons and wife and they laughed, too!

The shields always present a challenge unless you are fine with a 3D printed case with no RF shielding.? More than once, I have used a large generic RPi metal case and drilled and cut openings.? ?I have also resorted to metal boxes and short pigtails to bulkhead connectors for essential external connections.? I also have one 19 inch 1U rack for five RPis complete with an SD card jack and pigtail for each on the panel.? I am going to rework it for several dedicated RPis.
