Yup - but it looks good with the add on board. Is it just me or why is it that the "normal" raspb pi doesn't have eMMC?

[3dcandy]

Also how would you just get power and i/o easily as the big board ruins that
?

I wouldn't want eMMC when i can plug my own vastly larger (albeit sometimes less fast) storage in or adapt and change it whenever i want just by popping one card out and another in. Plus eMMC, apples to apples does just suck in the grand scheme.

perhaps - but the option would be nice like some other sbc's

By getting the correct connector and wiring it up to whatever things you need, using your own PCB.

Or, I suppose, you could try and unsolder the connector and directly wire things to the pins, but I don't fancy your chances.

I know - I just think it was a chance to bring out a nice tiny pc/sbc that was a little easier to make into projects. I'd like something in between say raspb pi 4 with an eMMC option

It's getting expensive.

That IO card looks rather nice, and annoyingly close to the Mini ITX format I have been wanting. Close enough I could probably 3d print my own case and be done. RTC is a nice addition too, and I have been waiting for IEEE 1588 supported phy.

That PCIe x1 socket though, network cards, SATA ports. Damn this thing has possibilities!

It's getting expensive.

$25 is too much? Tough audience The equivalent capacity parts are the same cost as the Pi3, you just get the option of spending more for something more capable.

I don't think thats ever been something they consider.

The compute boards were their "answer" to people "needing" something that provided a smaller or alternative layout to the standard Pi. That is, you develop your own idea and bolt the CM into it.

When the Pi first launched, there were all sorts of people "arguing" and "demanding" that they needed the Pi to be released with all sorts of additional options because "they had a business idea" and using the Pi was "necessary", ie they didnt have the funds or technical skills to make their own hardware and wanted to piggy back off something else.

Yet, weirdly, every time I see a project that should use the CM, it has a full sized Pi in it, the Pi-Top for example. As a result you have a cheap and easy to get going, at the "cost" of it being rather thick.

Can't really do much without that IO board - so: $25+35=$60
And these days 1GB (or even 2GB) is simply too little..
+5 for wireless, +20 for 4GB, even if ignoring eMMC: 50+35=$85..

But you arent supposed to buy that for "general use", you buy a regular Pi 4.

The IO board is for development of your own hardware that you intend to embed the Compute Module into, as such, you buy 1 and then many CMs, which you then embed in your own box with its own IO ports etc.

Whilst true for desktop style use and mucking about (my Pi4 has the biggest ram size you could buy on release day), these are intended for embedded applications. The machine I work on for a living has 1GB of ram, and we are only using about 300M of that.
