5V Power Converters

[Didier B]

... Hey Didier B did you add any circuits to the buck converter. Could send me a link?
I would like to add a power board so i can avoid using the micro usb connector on the  RPI and feed power to the 5v pin.
I removed my pico usb board. I want screw terminals for 12V in
The usb power option works fine behind a tv but i dont want it to come loose when i am getting beat by waves.

Hi ddelorme,
The DC converter I use is the XL4015 DC-DC Buck Converter Step Down Module Power Supply Output 1.23V-36V 5A
I put hot glue on the base of the choke to avoid possible trouble with the boat beating in the waves. I set the output to 5,2 VDC,
and put some nail varnish on the potentiometer screw.
I' have used this for one year in my 3 configurations and it worked lke a charm !


Regarding the use of USB micro connector to power the Pi, I just hate it !
In fact I use the  Farnell element 14 Pi desktop.  It consist of one enclosure plus a Hat extension which offers the following smart features :

• mSATA SSD port ;
  
• Safe power shutdown facility ;
  
• RTC (not usefull with OP) ;
  

If anyone is is interested (and anyone should be !) it is a good idea to read about in The maker space !
Important : that enclosure offers enough space to locate the power supply above module plus one MPU9250 and a barrel connector to bring the 12 VDC in !.

The pi is powered via the HAT extension through the GPIO. The HAT is supposed to be powered via the much hated micro USB Connector  ,
but I use the GPIO pin 2 and 6  to connect the power from the module. Some epoxy  glue into the f..... beeep! micro connector
will avoid any temptation to use that sh..BEEEP  in the future . . .
