We’re not in the habit of recommending Kickstarter jobs here at Hackaday, but when prototype components shows up on our desk, we just simply cannot assistance but engage in with it and produce it up for the audience. And that is particularly exactly where we uncover ourselves with the Turing Pi 2. You may possibly be familiar with the authentic Turing Pi, the provider board that runs 7 Raspberry Pi Compute boards at as soon as. That 1 supports the Compute variations 1 and 3, but a new layout was evidently necessary for the Compute Module 4. Not information with just supporting the CM4, the builders at Turing Devices have built a 4-slot provider board dependent on the NVIDIA Jetson pinout. The whole line of Jetson gadgets are supported, and a straightforward adapter helps make the CM4 work. There is even a manufacturer new module planned all-around the RK3588, which ought to be really outstanding.
1 of the design decisions of the TP2 is to use the mini-ITX variety-component and 24-pin ATX electrical power link, offering us the possibility to set up the TP2 in a tiny laptop situation. There is even a custom rack-mountable situation being prepared by the folks more than at My Electronics. So if you want 4 or 8 Raspberry Pis in a rack mount, this one’s for you.
@jp_bennett you signify a little something like this other than in 2U, and comprehensive mini-ITX aid? Take it easy, only point you will need is some patience… 😉 pic.twitter.com/vQcVCwmgDc

The Attractiveness — And the Dangers
“Wait, wait”, I hear you say, “There’s a lot of ways to rack-mount Raspberry Pis!” Undoubtedly. The form aspect possibilities are useful, but the true magic is the relaxation of the board. Separately controlled ability provide for all four boards from a one ATX energy supply can make for a incredibly cleanse solution. Need to have to reboot a hung Pi remotely? There’s the Baseboard Management Controller (BMC) that will do comprehensive ability management around the network. Which is the actual killer aspect: the BMC is likely to run Open up Resource firmware, and will power some incredibly intelligent features. Want UART to troubleshoot a boot dilemma? It’s accessible from all 4 nodes on the BMC. Want to thrust a new picture to a CM4? The BMC will include graphic flashing capabilities. Constructed into the board is a Gigabit network swap linking the Pis, the BMC, and two exterior Ethernet ports, all supporting VLANs.
On the other hand, not much of the BMC wizardry is really executed however on the evaluate models. This is the project’s biggest guarantee and the area it could go awry. Placing collectively a stable firmware with all the bells and whistles in the three months right before scheduled ship date may be a bit optimistic. I’m expecting a doing work firmware, with updates to refine the encounter in the months pursuing launch.
Then there is the expanded IO. The board comes with a pair of Mini PCIe ports, 4 USB3 ports, and a pair of SATA ports. This works via the PCIe lanes exposed by the several compute modules. Nodes 1 and 2 are connected to the mini PCIe ports, node 3 to the SATA, and node 4 to the USB3 ports. On best of that, a switchable USB2 port can be dynamically assigned to any of the existing nodes. Oh, and there’s an HDMI output from node 1, so even more possibilities, like working a Pi CM4 8GB as a desktop device. A late selection added to the Kickstarter bolts four NVMe ports to the bottom of the board, a single per slot, nevertheless not just about every compute module has the PCIe lanes to help it.
Now hold in head that I’m tests a pre-production unit (additional on that afterwards), and not all of the higher than is basically doing the job still. Really a couple of adjustments are slated for the manufacturing boards vs my unit, and the BMC firmware on this board is absolutely minimum. There is also the offer-chain troubles we’ve ongoing to protect here on Hackaday, but the TP2 has the edge of getting created in the course of the scarcity, so must be capable to prevent using challenging-to-supply components.
Now let’s chat about what this *doesn’t* do. This may well feel clear, but the Turing Pi 2 does not give you a single ARM equipment with 16+ processing cores. There is not ample magic onboard to make the devices act like a unified multi-processor computer system. I’m not positive there is sufficient magic any where to actually pull that off. Nevertheless, what you do get is 4 conveniently-managed devices that are great for working mild-body weight providers or Docker photos.
On the lookout for a platform for mastering Docker and Kubernetes? Or a area to host Gitlab, Nextcloud, and a file server? Probably you want to perform Nginx as a entrance-close proxy, and various gadgets jogging providers at the rear of it? The Homelab-in-a-box mother nature of the TP2 helps make it a useful preference for all of the over. And even although you just can’t moderately do all the over on a one Raspberry Pi, a programmable cluster of 4 of them does the work very properly. The VLAN aid means that you can increase virtual NICs to your nodes, and make an internal community. With the two actual physical Ethernet ports, you could even use your TP2 as your main router, on major of anything else it can do.
Actual-Entire world Screening
So what’s the real state of the undertaking? I have my pre-manufacturing board at this time booting a Raspberry Pi CM4, a Pine64 SOQuartz module, an NVIDIA Jetson Nano, and the Jetson TX2 NX. The Jetson Xavier NX experienced a quirk necessitating a slight board modification, but runs like a champ as soon as that was carried out. There are the ordinary warts of a pre-creation board, like more dip switches all around the area, and a couple quirks, like Ethernet only coming up at 100M for some devices. These are acknowledged challenges, and a good example of why you do a take a look at run of rev boards. The last solution really should have all the kinks labored out.
I’ve been monitoring ability attract, and the most I have managed to pull is a mere 30 watts of energy. This suggests a genuine-earth use situation, an off-grid compute cluster. The mini-PCIe ports should really enable for an LTE modem (Or you can use Starlink if you are *way* off grid). Incorporate a few cameras and set up the Zoneminder docker pictures, and you have a lower-electric power movie monitoring solution. Insert a RTL-SDR dongle, and the rtl_433 computer software listening to a solar-powered climate station, and you can monitor the weather conditions at your remote location, far too. Just for entertaining, I ran a Janus docker graphic on one particular of the Raspberry Pi CM4s on my TP2. Janus is the WebRTC server we have integrated into Zoneminder, and I was capable to dwell stream 12 protection cameras at 1080p, only using all-around 25% of the accessible processor electrical power, or a load of 1 on a 4 main Pi. It’s a testomony to how light-weight Janus is, but also a excellent case in point of one thing helpful you could do with a TP2.
The Kickstarter is in excess of, with far better than two million dollars lifted, but never sweat it, due to the fact you will quickly be equipped to obtain a Turing Pi 2. Purchasing will be taken care of by the Turing Pi internet site alone, keep tuned for the details. There will be a several months til the remaining revision of the board is concluded and transported, hopefully with some killer firmware and every thing doing the job accurately as advertised. Then last but not least there’s the alluring RK1 compute board, with up to 32 GB of ram and 8 cores of Arm goodness from the RK3588. That’s a minimal even further out, and may well be a 2nd Kickstarter campaign. I questioned about mainline assist for the RK1, and was instructed that this is a major target, but they are not particularly sure on the timing. There is rather a little bit of excitement close to this particular chip, so look ahead to the group doing the job together to get all the needed bits in place for mainline guidance.
There may perhaps be an surprising consequence of the Turing Pi 2 and RK1 employing the NVIDIA Jetson SO-DIMM connector. Visualize a handheld machine designed on the Antmicro open up resource Jetson Baseboard, that woks with multiple compute modules. I mentioned the Pine64 SOQuartz: Which is not an formally supported board in the TP2, but because Pine64 constructed it to the CM4 specifications, it clicks appropriate into the adapter card and performs like a champ. There is an fascinating chance that one particular or two of these compute module interfaces will acquire more than enough of a important mass, that it will get greatly utilized in products. And if everyone questioned, using the TP2 CM4 adapter does not magically enable booting a CM4 in a Jetson Nano provider board. Indeed, we checked.
So is the Turing Pi 2 for you? It’s possible. If you really don’t thoughts juggling several single-board personal computers, and the mess of cabling necessary, then maybe not. But if the skill to slot four SBCs in a one mini-ITX situation, with a BMC that will make life way a lot easier seems like a breath of refreshing air, then give it a search. The real examination will be when the finished product ships, and what form the help is in. I’m cautiously optimistic that it will not be terribly late, and that it will have performing OSS firmware. I’m seeking ahead to finding my hands on the ultimate product. Now if you are going to justification me, I feel I need to have to go set up an automated process for setting up aarch64 docker illustrations or photos.
