MintiPi Compute Module
MintiPi Compute Module
Hey,
Is it possible to get a Raspberry Pi Compute Module inside of a MintyPi?
If it is, it would be great if Helder could make custom parts for that option too.
Installation would then be easier, because you don't need to solder the Raspberry Pi to the PCB...
On the other hand I could not find information if the Compute Module actually has WIFI, which I think would be very useful for updates...
After all, I don't know if this would have any advantages for the MintyPi itself...

Re: MintiPi Compute Module
Physically and electronically it is harder and damn near impossible in this form factor

Re: MintiPi Compute Module
I can make it work but it would not fit in the tin and be able to close, the DIMM socket adds height which limits the battery that is usable in this and still be able to close the tin. Plus the power demand is higher and this needs some kind of cooling since it's fully enclosed the Pi would overheat quite easily.
Then I would have to fit many other parts on the button board since the CM3 is missing many things and that can be a challenge too for the size of the control pcb.
Maybe using something else other than a enclosed tin sure.

Re: MintiPi Compute Module
It's worth bearing in mind that there have been two different Compute Module models released to date, the CM1 and the CM3. Both are still available to purchase AFAIK. The CM1 has similar specs to the Pi Zero, so in theory it should work without requiring extra cooling or a larger battery. Whether it's worth redesigning to use the CM1 is debatable though, whilst it would be easier to fit it's more expensive than the Pi Zero.

Re: MintiPi Compute Module
If you take a look at an Altoids tin try to figure out how a CM1 would fit in there along with a button pcb, buttons, battery, charging board, screen, 3d printed parts, rear buttons, and a SODIMM slot for the CM1. The only possible way it could work is if you soldered the CM to the button PCB.ZenoArrow wrote: ↑Wed Nov 14, 2018 6:42 amIt's worth bearing in mind that there have been two different Compute Module models released to date, the CM1 and the CM3.

The mintypi is such a tight fitting build that if you have a single wire that's slightly too thick or out of place your tin wont close. If you have one solder ball that's too thick it will press and dent the battery. It's really a compact build.

Re: MintiPi Compute Module
In terms of making it work, it's plausible that it could fit as long as you used a single PCB for the button contacts, power and the SODIMM slot. It'd probably still be a tight fit (and may need a slimmer battery), but it doesn't seem completely out of the question. There could also be the possibility of saving space by moving the speaker to sit alongside the screen.dryja123 wrote: ↑Wed Nov 14, 2018 7:52 amIf you take a look at an Altoids tin try to figure out how a CM1 would fit in there along with a button pcb, buttons, battery, charging board, screen, 3d printed parts, rear buttons, and a SODIMM slot for the CM1.

Re: MintiPi Compute Module
Give it a go and let us know how it works when you get it sorted out. If you're able to figure it out you'd question if the effort was worth the results. Don't forget about cooling the CM3. The Pi0 thermal throttled a little in the latest iteration of the mintypi.ZenoArrow wrote: ↑Wed Nov 14, 2018 8:53 am

"Whether it's worth redesigning to use the CM1 is debatable though, whilst it would be easier to fit it's more expensive than the Pi Zero."
I'm not saying it's an ideal solution, all I'm suggesting is that it could plausibly be done.
If I were to spend my time on a Minty Pi-esque device, I'd prefer using the FleaFPGA Ohm (or some other FPGA-based device that is of a suitable size), where at least it'd be different enough to warrant the effort:

Before you take this the wrong way, I have very little interest in making that effort, and I have plenty of other projects I'd want to complete first.

Re: MintiPi Compute Module
Thanks for the suggestion but if you are expecting me or someone else to go to great lengths to prove it can be done and if it's more cost effective (which it isn't) then you will be waiting a long time.
I don't mind a suggestion about things but let's be realistic here and take the advice from the people who have designed the thing that the effort is not worth it and there are many limitations because of trying to fit it into a small tin. If this was being made for it's own custom enclosure then sure it's very plausible but I also have other projects besides this one on the burner that I'd like to get to once this is out the door.
Spending time "trying" to please everyone who has a great idea is not worth my limited time to invest to have something that is going to be arguably more expensive and has less playtime. To be honest not all N64 and PSX games or other consoles play perfect on a CM3 so wishing for a CM3 mintyPi just to play a few extra systems is not going to happen, better with a GBZ CM3 build to be honest.
