Raspberry pi powersupply change from micro usb to dc power plug

Former Member

Hi!

As topic suggests I want to change the powerconnection from the flimsy micro usb to a sturdy dc power plug.

Is this doable?

 

I was thinking something in the line of DC kontakt 2,5 mm chassi > DC-kontakter | Kjell.com

 

Thanks in advance

  • I have built a small buck power supply (using LM2596) that can take input voltages (through a DC connector like in here DC kontakt 2,5 mm chassi > DC-kontakter | Kjell.com) from 4V up to 40V.

    The PSU is built onto a small PCB which is mounted on a couple of plastic risers (~1.5cm in height) tight with screws on the 2 mounting holes of the RPI.

    Since this PSU can supply 5V and 3A, all the power supply issues that used to appear when using a phone charger as a PSU (5V/700mA) and USB hot-plug have disappeared.

    Now, I can plug into the USB even external 2.5" hard-drives with no danger of a brown-out reset of the RPI. For me, this solution works best.
