Powering the Raspberry Pi 4

Looking for ways to power the Smartipi touch 2.
Looking on here https://smarticase.com/collections/all/products/smartipi-touch at the Y splitter to power the pi 4 and the 7" touchscreen. What is a good extension to add between the Y splitter and the power supply https://www.amazon.com/gp/product/B07TYQRXTK/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 to get more length.

get a longer power brick … don’t do it like this…

What’re u saying longer power brick, u mean a longer extension, that what thought getting a 6ft long type-c extension between the power can and the Y splitter that goes to the Smartipi.

I’ve been using a Pi with 7” touchscreen for over a year now. I first connected power to the two devices via a splitter such as you suggest. My device never worked reliably until I removed the splitter and powered the Pi and display on separate power supplies.

i have a pi 4 4 gig and 7” touchscreen on a 2.5 a usb-c and runs oke… but no splitters or extentions… but i have no hat’s … only on usb my dragonfly dac… and a ssd usb stick with 256gig .


u mean a longer extension

no i mean a power brick i already said don’t do that because your 5 + 6 ft will be to long and you will get a power drop ( loss) from it … so if they say shorter then 10ft they mean not 11ft…but 9ft or less.

and what @Fylb says makes sense …
2 power separate supplies or shorter usb-c cable and a longer power brick…
( how long or short the brick is makes no diffrence because of the high voltage…
with low voltage you have less lenght to play with…)

I see this here on Amazon https://www.amazon.com/Retropie-128GB-110-Games-Raspberry/dp/B084VH6KX1/ref=sr_1_3?dchild=1&keywords=retropie&qid=1607661396&sr=8-3 128GB with 135,000 fully loaded games on it. So can u actually put that many games on a 128GB.

it’s a card with that many but you will find a few great and mutch low level games
( btw if you don’t have the orginal at home your not legal buzy…with this… )

so here’s my pi up ad going, now i just have to wait to get the RemotePi board in.

Another thing on here https://emulator.games/roms/sega-genesis/ at the end of the names of the games (JUE) what does that mean

nice stacked pile of pi you have the same cooler as mine :slight_smile: works great …

a bit off-topic here but here we go :wink:

(U) = US Rom
(E) = Europe
(J) = Japan
(G) = German
[!] = Verified good dump
[a] = Alternative version
[b*] = Bad Dump [image]
[f*] = Fixed to run better on copiers or emulators
[h*] = Hack
[o*] = OverDump (sometimes bad, sometimes good)
[m*] = Multilanguage

Video System: PAL = Europe/Japan. NTSC = US

and as cherry on your pi … there is a new release of the youtube plugin released…

In the photo above is my media player connected to my TV, i got that better looking that before.
The other Raspberry Pi 4 that i have for my Volumio music player

is it hard to solder a header to the HiFiBerry board and if not what size soldering wire do i need

if soldering is hard go to a repair shop ask if they would help you…or a friend who can do it…
the normal things i do my self but smd is to small for me…but a header is to do
i do already some soldering and have some tools to fix it, if it runs to the other pins solder wick wire and soldersuck tool to remove and you need flux too i use 1mm soldering wire

soldering lose wires is harder then soldering a header.

i use for now just ali stuf 2% flux diam. 1mm cf-10 / model b-2 / 63/37 extra flux is needed for a good flow. and some alcohol to clean it.

do u know what size soldering wire to use when soldering pin headers to a Pi or to a HiFiBerry. is it be about 113grams or what

on here https://www.amazon.com/gp/product/B0146DJR9Q/ref=ox_sc_act_image_4?smid=A34K5WF5Z9R33P&psc=1 do they make other sizes where the wings fit around the insulation of the wire.
I got some 26 awg silicon wire and bought these here https://www.amazon.com/dp/B0897KGG59?psc=1&ref=ppx_yo2_dt_b_product_details
the wings of the pins won’t fit tightly around the insulation of the 28 awg silicone wire.

it’s saying it’s for 21 awg, why do you use 26 awg or 28 awg?
that would be like putting a banana in a keyhole… it doesn’t fit…

26-28 awg is smaller then 21 awg so one of them two would fit https://www.amazon.com/gp/product/B0146DJR9Q/ref=ewc_pr_img_4?smid=A34K5WF5Z9R33P&psc=1.
these here https://www.amazon.com/dp/B0897KGG59?psc=1&ref=ppx_yo2_dt_b_product_details just won’t fit around 26 awg silicon wire, i know i tried many times, the two wings on the pin that wraps around the silicon insulation to grip the wire good just won’t wrap around it. do they make the pins with different size. I tried looking at the pins on Amazon but just won’t show, maybe a few. So do the pins have a name JST Xh for GPIO connection.

I been looking for these pins https://www.amazon.com/gp/product/B0146DJR9Q/ref=ox_sc_act_title_6?smid=A34K5WF5Z9R33P&psc=1 what are the name of them, i been searching online but couldn’t never find them

i never used them, but this should be the names of them

  • 100Pcs Female Pin Connector Terminal 2.54mm Pitch for Dupont Jumper Wire Cable
  • 100Pcs Male Pin Connector Terminal fit 21awg for Dupont Jumper Wire Cable

they are male and female so you could connect them.

but what are you trying to create?

short jumper wires. See, the way i have my raspberry pi for my media player set up, is why i have to create short gpio wires from the remotePi board to the GPIO pins.

i would use :

40 pins Rainbow GPIO cable extender male/female

40cm if you need longer there is even 60 cm (shorter is always better )
