5V Switching Power Supply 14.40EUR

+ Shipping / Versandkosten

On the boat or in the car we have easy access to 12 Volt power. A lot of little gadgets need 5 volts supply though - things like GPS mouse, microcontroller, USB-hub etc.

Often a linear 5 volt regualtor is used to reduce the 12 Volts to 5 Volts. This linear regulators just transform the excess energy into heat. This is not exactly efficient.

We made a little pcb with an integrated switching regualtor. The switching ruglators are much more efficient. They produce less heat and therefore they save energy - valuable energy on board of a Sailboat.

With tihis switching regulator we have a power source for 5 Volt and up to 2.5 Amps. The 5 Volt output is short circuit protected. No more blown fuses. Just fix the short circuit, and the regulator is ready again.

This regulator stays a lot cooler that the linear regulators. .

The board has 6 screw termimal to connect the wires. 2 terminal for 12..16 Volt input, 4 terminals to connect two of your gadgets.

The board dimensions are 49mm x 47mm.
It has 4 holes to mount it securely.

We used this this power supply at an input voltage of 14.5 volt and a load of 1.4 Amps. It get's a little warmer than handwarm. Try this with an linear regulator. It'll get really hot.

1.5 Amps is about the operating load we recommend.
It's no problem to draw 2.5 A - but with 2.5 A even the switching regulator get's hot.

So - for a short period of time ( a minute or two ) it can easily provide 2.5 A. But for standard operation we recommend to use not more than 1.5 A.

The regulator itself is protected against over temperature. When the temperature get's too high, it will reduce the current. So the regulator will not get damaged.

Our recomendation !! Operation current max. 1,5 A !!

Hello Frank Works as advertised. Thank you very much !!! One note: When you compile the source code on one machine and want to copy it to another you still need to install qt5 and the libraries but do not need to compile it again. I needed to change the file permission on the new device to allow execution: pi@raspberry:~ $ sudo chmod 0755 stConfig Obviously it needs to be executed in a graphical environment. Since I use my raspberry headless i was able to run it in a x11vnc session perfectly. Thank you again so much !!! Ralf


Multiplexer Config tool running on Raspbeerypi 3 [img:2d0cf14502][/img:2d0cf14502] Install QT5 development files : [code:1:2d0cf14502] sudo apt-get install qt5-default libqt5serialport5-dev libqt5websockets5-dev [/code:1:2d0cf14502] How I compiled it : Click [url=]---HERE--- to get the sources [/url] [code:1:2d0cf14502] unzip cd stConfig qmake make ./stConfig [/code:1:2d0cf14502] please let me know it it works on your RasPi Frank


Hallo Auch wenn ich noch keine Erfahrungen mit QT5 gemacht habe kann ich gerne versuchen es mit den Sourcen zu compilieren. Gruss Ralf


Hallo, ich bin gerade dabei zu versuchen eine neue Version für den PI zu compilieren. Ist etwas aufwändiger. Ich habe hier mittlerweile QT5 installiert und nun muss ich schauen wie ich das zu einer lauffähigen Version mit allen benötigten Libraries packen kann. Alternativ - wenn die QT Entwicklungsumgebung installiert ist, sende ich gerne sie Sourcen. Gruss Frank


Hallo auch von mir ein riesiges Dankeschön für den gelungenen Muxxer. Ich betreibe ebenfalls den RPi 3 als Nav-Computer an Bord meines Segelbootes und würde diesen gerne zum Konfigurieren des Muxxers nutzen. Bei mir startet stConfigPi ebenfalls nicht. Im Desktop Mode tut sich gar nichts und im Terminal mode gibt es den folgenden Fehler: pi@raspberrypi:~ $ ./stConfigPi Segmentation fault Ich habe qt4 wie folgt installiert: pi@raspberrypi:~ $ sudo apt-get -y update pi@raspberrypi:~ $ sudo apt-get -y install qt4-default qt4-dev-tools qtcreator Da ich nicht weis welche libraries benötigt werden habe ich gesucht und die Folgenden installiert: libqt4-dbg libqt4-dbus libqt4-declarative libqt4-declarative-folderlistmodel libqt4-declarative-gestures libqt4-declarative-particles libqt4-declarative-shaders libqt4-designer libqt4-designer-dbg libqt4-dev libqt4-dev-bin libqt4-help libqt4-network libqt4-opengl libqt4-opengl-dev libqt4-phonon libqt4-ruby libqt4-script libqt4-script-dbg libqt4-scripttools libqt4-sql libqt4-sql-mysql libqt4-sql-odbc libqt4-sql-psql libqt4-sql-sqlite libqt4-sql-sqlite2 libqt4-sql-tds libqt4-svg libqt4-test libqt4-xml libqt4-xmlpatterns libqt4-xmlpatterns-dbg libqtassistantclient-dev libqtassistantclient4 libqtconnectivity1 libqtcontacts1 libqtcore4 libqtcore4-perl libqtcurve-utils2 libqtdbus4 libqtexengine-dev libqtexengine1 libqtfeedback1 libqtgallery1 libqtglib-2.0-0 libqtgstreamer-1.0-0 libqtgstreamer-dev libqtgstreamerui-1.0-0 libqtgstreamerutils-1.0-0 libqtgui4 libqtgui4-perl libqtkeychain1 libqtlocation1 libqtmessaging1 libqtmultimediakit1 libqtnetwork4-perl libqtorganizer1 libqtpublishsubscribe1 libqtruby4shared-dev libqtruby4shared2 libqtscript4-core libqtscript4-doc libqtscript4-gui libqtscript4-network libqtscript4-opengl libqtscript4-phonon libqtscript4-qtbindings libqtscript4-sql libqtscript4-svg libqtscript4-uitools libqtscript4-webkit libqtscript4-xml libqtscript4-xmlpatterns libqtsensors1 libqtserviceframework1 libqtsolutions-soap-2.7-1 libqtsysteminfo1 libqttest4-perl libqtversit1 libqtversitorganizer1 libqtwebkit-dev libqtwebkit-qmlwebkitplugin libqtwebkit4 libqtwebkit4-dbg libqtxdg0 libqtxdg0-dev libqtxml4-perl Ich habe auch versucht QT Creator nach folgender Anleitung abzusetzen: Aber stConfigPi ist ja schon compiliert und sollte im Desktop Modus nativ laufen, korrekt? Ich wäre Ihnen dankbar, wenn sie die Benutzung des Raspberry Pi Config Tools noch kurz erklären könnten. Vielen Dank für Ihre Unterstützung Ralf


Nema Bridge to Wifi to IPAD

Hi I have just completed interfacing the SeaTalk NMEA Bridge128SD with a USR=WIFI module to stream the data on WiFi via the RS232 port. I do all my offshore navigation on an IPAD but then discovered not many racing Apps use wifi, most use bluetooth. I was considering this when I came across an interesting page on Zifigo who make Iregatta offering a limited number of beta test vesions. Looks like an app is on the way, I am hopeful of getting one to evaluate. Maybe some other yacht racing members may find this link interesting. The SeaTalk NMEA Bridge128SD is a well made solution. I am looking forward to playing with it and the race info it provides. Best regards


I can't download the latest firmaware version
Well - I just tried it again and it worked for me. If you still have problems to get, just send me a mail and I can sent it to you. Frank


I can't download the latest firmaware version


Thank you but I've not receive your mail Can you send it again ?


Apparently this did not ever make it into a product. I'd still be interested in one, so any other advice or pointers? Thanks, Harri
