I am planning to by a Picade soon and I really want to use the 12.1 inch screen. Hard to find stock but I see some that were recommended from this forum off ebay. I will provide the link below. From what I read also Pimoroni has a possible new 12.1 inch coming soon. I read the specs either way for a 12.1 inch screen it needs a 12v power supply. I did some research and I found a power supply on amazon that can provide 12v for the screen and also has a 5v 2.4A usb port. Can someone give me some fed back to see if this would work. Just to clarify I want to use this power supply for a 12.1 inch screen and the usb port (5v 2.4A) for the Pi 3.

Hi Same way the screen in the Picade kit connects to the USB port using the supplied cable which as a USB one end and a JST connector the other. Cheers Paul ---

The cable that is USB to barrel 5v to 12v I had to buy from amazon to be used with the item in the picture below. Now there is a cord that came with the full kit as a part of the 8 inch screen, The 12.1 inch screen needs 12v so that is why I bought cord from amazon. I will try the cord that came with the 8 inch screen which is a USB to JST power cable. ![](https://us1.discourse-cdn.com/flex016/uploads/pimoroni/original/2X/2/2446cebd0e94ab68a701f8334172e48cf038a5f6.PNG) ![](https://us1.discourse-cdn.com/flex016/uploads/pimoroni/original/2X/f/f15cdf30910bdd45e577140f5333318a70994bcf.PNG) USB to JST power cable ![](https://us1.discourse-cdn.com/flex016/uploads/pimoroni/original/2X/4/4cf8d3cd6bb5d8d796724d59dc8a0de574a197a5.PNG) ---

Hi there! Thank you very much for all the useful info you have given. Have you had a chance to try the USB-JST cable that was included with the 8 inches screen with the bigger one? Is your 12" set up up and running now? Any changes you may have made in the meantime? I want to move to the 12" screen as well next autumn, so I’m beginning to prepare the shopping list for all the parts needed :-) ---

No the USB-JST did not work at all for the 12.1 inch screen. It didn’t even turn it on. I am thinking it is only regulated for 5v. The 12.1 inch needs 12v 1A at least. I went with the USB 5v to 12v barel from [amazon.com](http://amazon.com) and it works fine but it gets really hot after long play time. I didn’t want to risk anything so I just went with a second power source to use the barel connector on the screen pcd. I know it’s not the best having to plug in 2 plugs but hey I know the Picade/screen will be safe. I want to try another USB 5v to 12v from Adafruit. It may work better. Let me be clear. Maybe another USB-JST cable may work but just not the one that came with the 8 inch screen. Maybe there is another for 12v. Here it is what I may go with soon below.

I am going to save my 8 inch screen for a new Mini Picade Pimoroni is coming out with sometime soon. I saw it on the Bilge Tank [Mini Picade exact fit 8inch screen](https://www.youtube.com/watch?v=_oPj-sVWDus) forward to the 25:47 mark of the video. ---

Thanks for the info on this. Having seen how good your 12" screen looks I’m sure it’s my next upgrade - and that’s interesting news from Pimoroni - and having a future use for my old 8" screen is further justification for an upgrade! Two power supplies wouldn’t be too bad an option - but can you confirm, when you power down the Pi, does the (still powered) screen go into a standby mode by itself due to no longer receiving a signal? Thanks ---

Hello. Yes like 2 seconds after the powerblock shuts the pi off the screens shows no signal message on a blue screen and shows no display like a standby mode. Then I unplug the screen power source.
