Re: Power Pi 4 or 5 from 12 volts

 

While this is a response to an old thread, I think it's relevant.

I just received a marketing email fro GeekWorm that includes a discount on
their X1203 5.1V 5A UPS Shield for Raspberry Pi 5 Series

Regular price: $46.00
Sale price: $41.00

Overview:

X1203 is an innovative uninterruptible power supply (UPS) expansion board
designed specifically for the Raspberry Pi 5B. With its advanced features
and robust power backup capabilities, the X1203 is perfect for even the most
demanding Raspberry Pi setups.

Reliable Power Backup: The X1203 provides a stable 5.1V 5000mA power backup,
ensuring uninterrupted operation of your Raspberry Pi. Whether you are
running resource-intensive applications or powering multiple peripherals,
the X1203 delivers reliable and consistent power supply.

Enhanced Power Management: One of the standout features of the X1203 is its
enhanced power management system. It intelligently monitors the power status
of the Raspberry Pi and automatically cuts off power when the Pi is shut
down. This helps optimize battery life by entering an ultra-low standby
power consumption mode. It ensures efficient operation and maximizes the
lifespan of the UPS battery.

Seamless Power Switching: Equipped with AC power loss and power adapter
failure detection, the X1203 seamlessly switches to backup power in the
event of a power outage or power adapter failure. This feature guarantees
that your Raspberry Pi remains operational and protected from unexpected
power disruptions.

Convenient Features: The X1203 offers convenient features such as auto
power-on, enabling your Raspberry Pi to automatically boot up when power is
restored. It also supports full power-off from software, allowing you to
safely shut down your Raspberry Pi without manual intervention.

Fast Charging: With fast charging capabilities of up to 3000mA, the X1203
ensures quick recharging of the UPS, making it ready to provide backup power
whenever needed.

Flexible charging:
You can use either type-c or DC5521 to charge the battery. When using type-c
you can use the PD27W power supply that powers the Raspberry Pi 5, when you
use the DC5521 you can use a variety of power adapters in the 6-18V range.

Versatile Design: The X1203 is designed to be attached on bottom and don't
use the 40-pin header, enabling easy stacking with other Raspberry Pi
accessory boards. This versatility allows you to expand the functionality of
your Raspberry Pi and create enhanced applications tailored to your specific
needs.

Seamless Data Backup: The X1203 is compatible with our range of storage
products, providing seamless integration for safe and reliable data backup.
Your valuable data remains protected, even in the event of a power failure.

Enhance the reliability and performance of your Raspberry Pi 5B with the
X1203 UPS expansion board. Experience peace of mind with its advanced
features and robust power backup capabilities. Trust the X1203 to ensure
uninterrupted operation and safeguard your valuable data.

Warning:
When you use an external battery box or battery pack, please pay attention
to the positive and negative poles, generally speaking, the red wire is the
positive pole, the black wire is the negative pole

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?

Re: New to Raspberry Pi and this group

 

I have done an extensive search on internet for solutions to the problem I have been having. It seems to be specific to the FUNCube Dongle Pro + and GQRX on the Raspberry Pi. It seems to be a problem that many are having, not just me. It has nothing to do with how much current the FUBCube is drawing. It is about the same for all three SDR dongles I am using and the other two, the RTL-SDR Blog V3 and the Airspy Discovery HF+, all work fine with GQRX on the Raspberry Pi. I have tried a couple suggested solutions I found but none of them worked (when the FUNCube is started, the mouse and keyboard lock up). At this time I am giving up on using the FUNCube with GQRX on the Pi. Maybe it will work on another SDR program. I still have two other SDRmodules that DO work.

Re: New to Raspberry Pi and this group

 

I got curious and used a 12 to 5 volt adaptor with a USB-C plug on it. I have no way of measuring the current on a USB-C line. But I can measure the current on the 12 volt line. Current at 5 volts is probably slightly more than twice the 12 volt draw.

With the Raspberry Pi 4 with a USB keyboard and mouse connected to the USB 2.0 ports and an HDMI cable to a monitor, after it's booted up and in a quiescent state, I measure 120 mA draw at 12.4 volts to the adaptor. Plugging in each SDR dongle I have, one at a time, into a USB 3.0 port, I measure on the 12 v line:
RTL-SDR Blog V3 = 180 mA
FUNCube Pro + = 220 mA
Airspy Discovery HF+ = 190 mA

These do not look excessive to me and are well within the 3A maximum draw of the Raspberry Pi. I cannot imagine the USB ports drawing anything near their maximum capacity with those measurements. I don't think that's the problem. These are with the 32 bit Raspberry Pi OS. I installed the 64 bit OS on another micro-SD card and installed GQRX on it. I haven't measured the currents on that, but the same thing happens. The RTL-SDR Blog V3 and the Airspy unit continue to work fine when I click on "play SDR." The Funcube causes the mouse to freeze up. I think there is some bug in the software for the Funcube.

By the way, my laptop draws 5 amps at 12 volts. That's what I'm trying to get away from. It looks like the Raspberry Pi will be far below that current draw.

New to Raspberry Pi and this group

 

I just recently joined this group. I'm new to the Raspberry Pi and actually new to Linux. My original purpose for the Ras[berry Pi was to use it as a spectrum monitor for the IF of microwave transverters. This would hopefully take one unknown (the frequency) out of the picture when trying to peak a signal with a dish antenna.? My laptop is an energy hog and is also bulky. Not very conducive to microwave hilltopping operations.

I got a Raspberry Pi 4B. I found these instructions for installation of a program called Freqshow on the Adafruit website:


This seems ideal and exactly what I want. The only problem right now is that the Adafruit 3.5 inch PiTFT display is nowhere to be found. Everyone who carries them is out of them. So that project is on the back burner right now.

I successfully installed the OS for the Raspberry Pi on a 64 Gb micro-SD card. Then I found this site:


So far, I have successfully installed GNU Radio, GQRX, RTL-SDR, FLDIGI, FLRIG, WSJTX , JS8CALL and QSSTV on the Pi using the instructions there. I think it's successful because FLRIG connects OK to my FT897D using a CT62 USB cable.It seems more limited than what the webpage shows with installation instructions shows. I am only able to change frequency and mode of the radio, For some reason I have no controls shown for volume, squelch, noise reduction, etc. Maybe these aren't available for that rig in that program.

GQRX seems to work OK with the SDR dongles I have, except when I use it with the FUNCube dongle, the mouse locks up and I have to unplug the dongle to get mouse use back again. I'm not sure why that is, either. It works fine with RTL-SDR Blog V3 and Airspy Discovery HF+ dongles.

Hopefully some day the 3.5 inch PiTFT displays will be available again and I can start playing around with using that on the Raspberry Pi.

One of the issues with Linux is package management—meaning the software isn’t always kept up to date by the volunteer package owner. It’s pretty easy for the software to fall out of date, especially something like the fldigi suite.?

The good news is the fldigi suite is relatively easy to compile and install. Navigate to??and the source is there to roll your own. You’ll probably want to remove the fldigi suite before you start though.

The building instructions are at??for the Pi. There’s also a script to take care of most of this for you at??however I’ve never run it.

You should be able to download that last script, run it in a terminal session and have it build for you—but please post back if you are still having issues.

Thanks,
Dan

Re: 2B direwolf gpio errors

 

Another option is downgrading the kernel to 6.1.74 which was the last kernel with the deprecated GPIO. A lot more software will be affected for GPIO access and this fix will fix it for all
sudo rpi-update d86b5843d68b9972a5430a6d3da1b271cfc83521

Hello Jim,

A recent Raspberry Pi OS upgrade made many disruptive changes including deprecating the old way of interfacing to the GPIO pins.? To resolve this for Direwolf you need to compile a new Direwolf using the Direwolf DEV branch which will bring you up to the 1.8-D version:
