Raspberrypi has released its new CM3, or Compute Module 3, and ArsTechnica has the details.

The Raspberry Pi Compute Module is getting a big upgrade, with the same processor used in the recently released Raspberry Pi 3.

The Compute Module, which is intended for industrial applications, was first released in April 2014 with the same CPU as the first-generation Raspberry Pi. The upgrade announced today has 1GB of RAM and a Broadcom BCM2837 processor that can run at up to 1.2GHz. "This means it provides twice the RAM and roughly ten times the CPU performance of the original Compute Module," the Raspberry Pi Foundation announcement said.

This is the second major version of the Compute Module, but it's being called the "Compute Module 3" to match the last flagship Pi's version number.

[...] The new Compute Module has more flexible storage options than the original. "One issue with the [Compute Module 1] was the fixed 4GB of eMMC flash storage," the announcement said. But some users wanted to add their own flash storage. "To solve this, two versions of the [Compute Module 3] are being released: one with 4GB eMMC on-board and a 'Lite' model which requires the user to add their own SD card socket or eMMC flash."

Has anyone used one of these Compute Modules, and if so what for?

    Two surprises and a comment:

    1) Its in stock at Element 14, I think. I hope thats not preorder. The Zero was announced more than a year ago and of course its never been available, I checked a couple minutes ago at adafruit and nope.

    2) There exists a legacy print and paper magazine called the Magpi all about the pi thats been around for years.

    I've used a couple pi in various projects related to ham radio and 3d printing and just screwing around and every time over the last couple years that I've said "this would be a hell of a lot easier if the pi had..." has always ended with a req for more and better IO never more CPU power. I could really use built in wireless (like the pi3) or minimum dual SATA to make a nano-NAS or dual ethernet to make a firewall or ...

    I just bought a Zero 1.3 three weeks ago for $5. Currently using it as a PLC for home automation.

    Compute module never really interested me since it would require a socket and breakout board, while the zero has a simple through hole design i can solder directly into.

    And I could really use power-over-ethernet to clean up the implementation of many Pi based projects I have done / have in mind.

    What you need depends on your application space, I'm still muddling through with power bricks feeding the USB port where I'd much rather have the Pi connected to a single PoE ethernet cable at a remote location "doing it's thing," whatever that thing is. Some people laugh at this because they just plug into an existing available USB port to power on the desk where they deploy their Pi projects and don't even have to get a 2A brick.

      don't even have to get a 2A brick.

      For bonus "fun" which I've had to troubleshoot for a good time you can plug a pi into a 250 ma or 500 ma cell phone charger and it'll kinda halfway work sometimes or sometimes get into reboot loops depending on room temperature, oh its so much fun.

      From memory around the pi2 era it was easier to find a wifi dongle that worked with the pi than to find a USB charger that output enough current to run the pi. I was doing things like buying a USB powered AC plug in hub then plugging the pi in using a charging only (no data connection) cable.

    Check https://www.olimex.com/ [olimex.com] EU based (always try to get the VAT removed when dealing with EU companies), decent support (them, sunxi, armbian...), long term commitment for some of the chips (they got a deal with Allwinner, if they buy a full batch, they will made them even if old model), lots of GPIO via multiple 2*40 headers, even industrial temp range in some models. Mainline kernel support is there or on the way ( http://linux-sunxi.org/Linux_mainlining_effort [linux-sunxi.org] ), only big issue left is... right, video drivers. But for anything without screen, they are pretty good.

    SATA is going to be tricky, most chips designed for tablets/phones have one port at best. Same with ethernet. And those chips are what many of the ARM SBC use. Many of the Olinuxinos do have a SATA port. And real ethernet and USB, instead of "multiplexed" over a single real connection like RPi. Making a firewall would require a usb-ethernet adapter or using something like their SOM AM3352 EVB (slow 2*100Mbps, not same level of support than the Allwinner based SBCs).

    We received our CM3 dev kit this morning, but I think it was ordered from RS rather than Element14. There were only 73 listed in stock globally yesterday though.

    And yeah, for many applications a couple of SATA ports and a better Ethernet would be nice. A Raspbian without systemd would also be nice... *ducks and runs*

    You might want to take a look at the Beagleboard X15: https://beagleboard.org/x15/ [beagleboard.org]

    Its single eSata (and AFAIK a "real" eSata port, not a USB bridge), dual Gig Ethernet and three USB3, plus a couple of PCIe lanes wired to the IO headers. Wireless would have to be an add on, and it's pricey, but it's got connectivity to burn.
