Eben Upton had already mentioned the Raspberry Pi Foundation was working on a Raspberry Pi Compute Module 3 based on the same Broadcom BCM2837 quad core Cortex A53 processor and 1GB LPDDR2 RAM used in Raspberry Pi 3 board earlier this year, but few details had been provided at the time.
The module is still not available, but NEC Display Solutions Europe has already announced they are working on integrating Compute Module 3 into commercial displays starting with 40″, 48″ and 55″ models in January 2017, and up to 98″ by the end of next year, used for digital signage and presentation platforms.
The Raspberry Pi Foundation goes on to say they’ve been working on NEC project for over a year now, and they expect to release Compute Module 3 to the general public by the end of the year. Price and complete technical details have not been released yet.
You can also watch the video below with NEC announcing Raspberry Pi 3 module based Displays at the 7:43 mark.

Go get it working for digital signage, you just need minimal hardware: CPU, RAM, ROM of any kind, PMU and connectors.
For kernel software it only needs display driver working, maybe plus hardware video decoders.
Audio, wifi, ethernet, power-saving, camera, are all optional.
Yet that takes them over a year and is still not done.
With all those SoMs available all over the world, NEC picked this?
@dx Apparently you’ve never designed a new board, have a handle on the current market, or did board bring-up. 1) Depends on signage. Some of the level of sophistication they’re doing of late for signage/kiosk isn’t what you’re claiming. It’s not “simple” anymore, esp. if you’re doing video playback. 2) Display driver, audio, hardware video decoders- you need AUDIO if you’re doing video. 3) Everything but camera is **NOT** optional. This is my first clue you’re ignorant of quite a few things. It takes a bit of time to design one cheaply. Have you priced the SoM’s that are capable… Read more »
I thought the Pi Foundation was a registered charity with the purpose of furthering the “advancement of education of adults and children, particularly in the field of computers, computer science and related subjects”
With this push it’s becoming more of a tax dodge operation for funnelling SoMs to big players like NEC and others who sell _very profitable_ hardware.
Doesn’t sound very charitable to me.
@JM
The fact that their designs work beyond the “advancement of education of adults and children, particularly in the field of computers, computer science and related subjects” should be taken as good news rather than bad. There seem to be rather a lot of other companies taking the PI designs and using them for profit. Do you think Broadcom would be providing all the support it does if there was not a business advantage?
@JM Feed-The-Hungry type nonprofits often buy supplies from for-profit without a discount. They also pay their employees while taking advantage of volunteers. This isn’t all that different. I would put the Pi foundation’s particular type of tax dodge as the more benevolent kind. Somewhat similar to contractors funneling their taxes through donations to homeless-shelters which they themselves go on to build but not for a huge net profit. Compare them to the likes of Microsoft & Apple whom dodge their taxes through pc\tablet-for-every-child foundations which do nothing to aid the children’s education and much to do with Microsoft’s and Apple’s… Read more »
@JM A not-for-profit business is still a business. If people working at the Raspberry Pi Foundation were taking huge sums of money behind the scenes or directly off the top of sales then that would be wrong to do under the benefits of a non-profit organization. Selling to a for-profit business can gain more capital for the foundation as a whole, which can then be ‘funneled’ into expanding on the primary goal of education and new hardware development. It isn’t much different than the hordes of people who buy up all of the Pi’s when they are new so they… Read more »
@RK What is really happening is more like a building material supplier (or Broadcom) selling – exclusively since no one else can buy that chip – supplies to a shelter charity (Pi Foundation) who then goes and build houses with them. These houses are then picked up in bulk by a property developer, who adds some furniture and sells them for very good profit. Or imagine the Red Cross providing private medical services to a large insurer using their charity funds and volunteer doctors’ time. With no corporate taxes to pay, VAT exemptions – and tax benefits to the supplier… Read more »
@JM
to be honest, beside the price point, the rpi was never a good pedagogical context. It’s an ambiguous proposition, it mostly allows you to toy with the program / electronics interface, an extremely powerful arduino for half the price. But the internals were a mess, and no kid will ever learn anything about it. And globally it’s not even a good price either, rpi kit + lcd is often above a 2nd hand laptop. Yay recycling.
@dx @Nobody of Import I’ve worked on digital signage players in the past, and testing takes quite a lot of time, as this has to work reliably. We agreed with customers that if the platform could run 7 days in a row without issues, then it would be considered stable. Sometimes a bug comes up only after 5 days, so we have to investigate, and fix the issue, and repeat the test. NEC also mention something about IoT for their display, so I guess that means they get some data from the cloud, possibly the media files, or other metadata,… Read more »
In the UK several years back a company was just connecting a smartphone to a TV, with the TV stood on its side vertical. That was before Phablets where common. Have not a clue what they do now..
A few points stated by Eben Uptom from the video, not mentioned so far: 1) There will be future generations of RPi Compute Module (perhaps this is stating the obvious, but now it’s been said publicly) 2) Future compute modules (ie. CM4, CM5 etc.) will be electrically compatible with existing compute modules (ie. CM1 and CM3) – good news for NEC customers in terms of long term support and future upgrades, and also manufacturers of Compute Module devices such as Slice, whose customers can upgrade without throwing away the entire device 3) The “standard” CM3 will come with 4GB eMMC… Read more »

So why not connect 2gb ram 8gb emmc $30 Android tv box, what special is Raspberry bringing to the mix ?
@theguyuk Maybe because NEC wanted long term support which you’re not going to get from $30 Android box suppliers that change chipsets more often than they provide decent kernel releases. In addition, as solutions go the slot-in Compute Module beats an Android box all ends up. NEC could have stuck an RPi3 on the back of their displays, but they obviously didn’t want that – they wanted a fully integrated solution, and you won’t get that from any Android box supplier. But NEC aren’t stupid, they know their customers needs and that’s why they saw the long term potential in… Read more »
Sweet, a 98″ display with just 1920×1080 pixel (VideoCore 4 maximum output resolution).
@tkaiser
Even with a 98″ screen, when viewed from more than 4m, nobody will be able to tell the difference between FullHD and UHD – it’s accepted that there is no benefit to UHD at a viewing distance of 4m or more, even with 100″ displays.
http://i.rtings.com/images/optimal-viewing-distance-television-graph-size.png
These NEC displays are designed for signange, and to be viewed at distance.
They are not designed for your living room.
LOL, and just one single USB 2.0 connection to the outside will be there forever if backwards compatibility is an issue: https://www.raspberrypi.org/documentation/hardware/computemodule/RPI-CM-DATASHEET-V1_0.pdf
But at least 2 DSI and 1 x composite display output are available in addition to HDMI (1.3a)
@Frank
So will this have the over heating problems of the RPI 3 ? Or are Nec fitting fans?
How well is RPI doing 4K these days ?
Would I want my business on a computer every school kid knows how to hack or hack on?
Yeap nice secure IOT.
Funny reading: Secondary Memory Interface (SMI) “is not publicly documented in the Broadcom Peripherals Specification”, Display Parallel Interface (DPI) “is not documented in the Broadcom Peripherals Specification but documentation can be found here” (where?), SD/SDIO: “The first (SD0) is a proprietary Broadcom controller that does not support SDIO and is the primary interface used to boot” (so VideoCore brings up this thing and Linux on the ARM cores is just a guest as usual) “Currently the CSI interface is not openly documented and only CSI camera sensors supported by the official Raspberry Pi firmware will work with this interface” and… Read more »
@theguyuk: You really are spouting drivel now. (Oh, and fans will not be required). @tkaiser: All of that is known and nothing new. The VC4 work being carried out by Eric Anholt will provide more standard and documented hardware access. NEC clearly don’t have an issue with the current state of play, or what the hardware embedded in their displays will be capable of in 2023 (remember, future RPi Compute Modules will be electrically compatible – this is a promise from the RPi Foundation, do I need to spell out to you what this means?)

@Frank Of course you don’t have to spell out what ‘electrically compatible’ means: future Compute Modules have to be as limited as those available today (maybe the CM4 will then combine VC4 with Cortex-A72?): As far as I understood all RPi SoCs so far are basically the same, younger generations benefit from slightly higher VC clockspeeds and ARM core(s) are exchanged in between. But the real features are dictated by VideoCore so without enhancing something there max DRAM will be limited to 1 GB, booting requires FAT16/FAT32 and so on? BTW: I don’t think that any of these limitations is… Read more »
@theguyuk
> I am not suprised RPI 3 heat issues, given modern cores.
And you’d be wrong, but I’m not at liberty to say how or why.
@tkaiser I guess I do have to spell it out. Electrical compatibility does not automatically mean VC4. The Compute Module makes available on the SODIMM connector every pin from the SOC. This includes the HDMI pins, the electrical characteristics of which will be the same in the future as they are now (relevant protocols may change, but that’s for the SOC and display to negotiate). Future Compute Modules with HDMI capable of UHD resolution will use the exact same number of pins as current FullHD HDMI – it’s why you can plug your old HDMI 1.2a cable into a HDMI… Read more »
@Frank
Thank you for the clarification (and the insights of course). Is the same sort of upwards compatibility also possible for the USB connection? Negotiating USB 3.0 SuperSpeed?
@tkaiser This would depend on the logic implemented directly on the Compute Module IO board (that which the Compute Module plugs into), which will make upgrading less likely. This isn’t to say future Compute Modules couldn’t/won’t support faster USB and Ethernet, just that current IO boards will not, regardless of the Compute Module in use. Currently the IO boards use the same LAN9514 IC in the RPi3, which supports USB 2.0 and USB-to-Ethernet bridging. Perhaps future CM IO boards could implement faster USB and Ethernet – as future RPi SBCs no doubt will – as long as the interface between… Read more »

I have a comment waiting moderation, which links to a running thread on over heating RPi 3, when in a enclosure and doing 1080p video.
So when is someone going to make a pin compatible Allwinner A64 compute module and sell if for $15? Should not be a problem at that price point to make. How much is the RaspPi one going to cost? $50?
A64 has roughly the same performance. Let people build the cluster infrastructure aimed at the Pi3 compute module, then simply use the A64 module. A good sized cluster will be $1,000 cheaper with A64.
@theguyuk
I made no comment about the reports of the RPi3 SBC overheating. I simply said you were wrong (about your expectations). Read between the lines.
@tkaiser
The 98″ version is planned for the end of 2017. That’s odd the smaller version will be available in January, but the larger one will take a full year to develop. One reason for the extra development time could be that it will support 4K via Compute Module 4. So I’m expecting Raspberry Pi 4 sometimes next year (February 28?), followed by Compute Module 4 later with a 4K/H.265 capable SoC.
@Jon Smirl
It would be a mistake to not expose RGMII since GbE is A64’s fastest interface.
@Jean-Luc Aufranc (CNXSoft)
I was just interested hearing about VideoCore future. So there will be better resolution and codec support but clearly the ‘one USB connection to the outside’ limitation remains and most probably next generation will still be limited to USB2 since chicken-egg problem (carrier boards should make use of USB3 before). I’m really happy that it seems we’re getting HW accelerated video encoding now on cheap Allwinner SoCs so the last remaining use case for RPi SoCs has gone then too.
@Jean-Luc Aufranc (CNXSoft) Nice heat for cooking then. Since Roku recently used BMC Chips are their 4K boxes BMC ? Interesting Roku review quote ” Some of things that seemed to be wrong with the Roku 4 revolved around its energy consumption: the device ran constantly (and ran hot); wouldn’t always turn on after a 30-minute energy energy saver; and, once off the Roku 4 wouldn’t turn on via the remote. Roku Ultra, at least in the 24 hours we’ve been running it, doesn’t run as hot as Roku 4 ” ref http://hd-report.com/2016/10/14/review-of-the-roku-ultra-with-4k-hdr/ Is this the source of possible 4K… Read more »

You try to use a device using a Sigma Design SoC (do a google search for STV7723A01) to do Broadcom bashing. Congratulations.

@Theguyuk Your Broadcom bashing gets boring since really no one needs those overprized Cogent.design aluminium enclosures (they also sell one for the ODROID-C2 where it’s really absurd since the stock heatsink is pretty efficient and requires huge amounts of work to be removed without causing damage). In a digital signage situation you control the codecs to be supported, the most demanding task will be h.264 decoding and this happens entirely on the VC4 HW accelerated (yeah, temperature increases and the amount is the same on any VC4 based SoC regardless of ARM cores used and clocked). No one will be… Read more »
