CM4 Carrier board as a separated product to help other projects?

AssetBurned — Tue, 27 May 2025 22:49:58 +0000

Hi,

I am a bit confused if the carrier board is now a real GPIO or not. If it is it would be a great option to help other projects that are using Pi Zeros and struggle with RAM constrains but don’t want to go for a full scale Pi.

also in that case the more i/o from another topic here would be beneficial.

in that context it would then also be good to offer that Board also without a soldered pin header. That would give the full flexibility on how to use the board.

Possible Future PSVita/CM5 Project

vynladon — Thu, 12 Dec 2024 19:33:52 +0000

What do you think the feasibility of supporting this project in the PSVita form factor in the future would be? I'm aware this was asked previously in https://othermod.com/forum/support-for-othermods-boards/how-viable-would-a-psvita-be/ but was curious if that philosophy had changed at all given the advances you've made over the years (plus the slimmer structure that the CM4/5 give over the old PiZero form factor). My main hope is to have a unit with dual joysticks as opposed to the single joystick of the original PSP (though the larger screen is a plus).

My other question is for the CM5 itself. The CM5 generates a lot more heat and uses slightly more power than the CM4. As such, an active (or much larger passive) cooler is advised for use. Is this feasible with the current system (or in a PSVita form factor)? Again I know this was touched on in https://othermod.com/forum/project-ideas/cm5-possible-upgrade/#post-1593

I'm just really curious as to all of this. I'm looking at trying out the PSPi project myself and would love to help out however I can (I'm just not a hardware engineer and very unfamiliar with designing this kind of project lol - also feel free to delete this if you feel it overlaps too much with other topics)

More I/O on the CM4 carrier board?

gammax — Fri, 26 Jan 2024 08:24:42 +0000

What about other I/O on the CM4 carrier board Or a daughter board for more i/o that attaches to the door.

At least usbc for higher transfer rates and port maybe a Mini/ micro hdmi...

cm5 possible upgrade

moserah — Thu, 16 Nov 2023 11:16:25 +0000

I was wondering if with the probable advent of the CM5 for 2024 and PCIe support, it would be feasible to implement a PCIe connector for NVMe on the board to get rid of the unreliable micro SD, furthermore it wouldn't be a bad idea to implement a dedicated connector for a possible sub audio channel given that it is not possible to keep the umd reader, someone would like to be able to install a 44 mm driver on the back of the psp and create a 2.1 system.

diy handheld with win 10

Ron Plank — Sun, 13 Feb 2022 00:17:19 +0000

great scott; on his youtube channel used a latte panda which comes with arduino for controls, and build a DIY hand held game with Win 10. i was hoping for something like that but a little cheaper and maybe use an exciting game shell. just thinking.

Is a microHDMI port possible on a future board?

WhiteBeard — Thu, 03 Feb 2022 21:46:59 +0000

Hello, I'm just curious if it would be too difficult to put a micro or mini HDMI port on a future board revision. Possible if the IR port was removed?

Thanks, Keep up the good work.

Raspberry Pi A+ build

chadnelson31 — Sun, 24 Feb 2019 01:43:02 +0000

So I bought one of the new Raspberry Pi 3 A+ to build a portable retropie/Linux handheld. I found an old psp I had laying around that was used for parts and decided I might be able to use it as the housing for the project.

I did some research and stumbled across your site and was blown away with how much work you have done towards building the handheld (Thanks a ton for documenting everything!). I saw you had built custom boards to work with the Pi zero with version 3 and 4 of the build so I decided to try and follow 2/2.1 and incorporate it with the A+ instead. I guess I have a couple questions:

1. Is there anywhere where I can either purchase or get the files for the 24pin breakout board used in version 2.1?

2. I saw you mention in another thread regarding the Raspberry pi compute module that you would consider the A+ because it incorporates power regulation. How would that change the 2/2.1 build in regards to components needed?

(This is my first custom project so I'm learning along the way and I appreciate all the time you have taken to help me and others!)

Use the compute module 3 inside the psp

thirday95 — Mon, 22 Oct 2018 22:38:11 +0000

would it be possible to create a board that would support the conpute module 3? The reason why i am asking is because it has the same power as a pi 3 so you could emulate a lot more (i have a freeplay cm3 and can run a bunch of n64 games on it)

Pi zero WH

Fuzzybat23 — Mon, 14 May 2018 12:36:53 +0000

It'd be awesome to have a pspi board that can work with the new Pi Zero WH. This one has header pins like the full sized Pi. Granted, this would mean either the pins on the pspi board would need to be reverses, as the pi zero wh would need to be installed upside down from how it is installed now, or a ribbon jumper could be used to connect the two together.

Raspberry Pi Compute Modul 3 Lite as replacement of Zero

Secon — Wed, 26 Jul 2017 22:41:13 +0000

Hi I write because I like the idea to get a little more out out of the PSP.

But I see a basic problem, the Pi Zero does not provide very much performance for emulation. But this could change if you were to replace Pi Zero with a Raspberry Pi Compute Module 3 Lite, this would allow more connections and more power for your project and the possibility to swap the core of the platform quickly.

And the last point it would greatly expand its market.

I hope on feedback.

Best regards
