You're not finding anything because you're searching for "Raspberry Pi Compute Units". They're not called that in the article you linked, or anywhere else.
You need to search for "Raspberry Pi Compute Modules". You should get hits for Newark/Element 14, etc., and you'll also find them on Adafruit using that search term.

The Raspberry Pi Zero is produced and distributed by the Raspberry Pi Foundation directly. The other Raspberry Pi boards have commercial partners involved with their sales. These partners improve the availability of the other boards, at the cost of incorporating a profit margin for everyone in the supply chain.
The Raspberry Pi Zero is still deliberately ...
In a nutshell, the RPi family of devices does not provide a method to keep power alive while finishing a write operation on the SD card.
If during a power disconnection the memory card is in a write operation, there is a high chance that one or more sectors will be unexpectedly damaged.
My personal opinion is that the Raspberry Pi Foundation should ...
The Pi Compute Module's stereoscopic support causes captures (and video recordings) to produce frames containing images from both attached cameras, either side-by-side or top-and-bottom, depending on how the camera was configured on startup.
There are various restrictions on resolution (and other things) when working with stereoscopic mode, which 6by9 ...
Eagle PCB is a great PCB CAD design software. There are no pre existing designs in CAD as this is usually intellectual property, and cost allot of time and money, if you carry on reading you will understand better. You may consider trying it your self and once you have a prototype you can get a consultant to fix er up for cheaper.
It takes some getting used ...
Before I answer your question, I'm going to include the following disclaimer. I am not a lawyer. I have some knowledge of business law, but my expertise is limited, and solely within the scope of the United States.
First, I'd say we need to consider looking at what the Raspberry Pi foundation states for its IP (intellectual property). In 2012 they ...
I found that using a read-only file system was a fine way of dealing with file corruption errors on classic Rpis.
In your case, you may at least try to put the /boot partition in read-only mode. Edit your /boot/cmdline.txt file to add at the end :
Then edit the line defining "/boot" your /etc/fstab :
/dev/mmcblk0p1 on /boot type vfat (ro,...
This is only the first link I found mentioning it, but yes a new compute module is planned and has been mentioned in several interviews with Eben Upton (head of the Pi Foundation - I don't think it gets more official).
In May 2016 Lattice Semiconductor published a guide (2:1 MIPI CSI-2 Image Sensor Aggregator Bridge Demo) for a Raspberry Pi dev kit used with the CrossLink Master Link board featuring a Lattice LIF-MD6000 device.
There are instructions on page # 8 Chapter 4 (Hardware Setup), that describes the use of one Raspberry Pi's camera's oscillator to synchronize ...
Sorry, but it's not possible. Maybe future HDMI standards could implement this, but not now. I guess we'll start using USB-C sooner.
As for the Intel Compute Stick, if You see the images explaining external ports, You'll clearly see that there is a Power port (micro USB) as well.
Another explanation comes from Intel website:
Put out the SD Card from the compute module and plug it into a card reader attached to another linux computer. Assuming the SD Card is seen as /dev/sdb on the computer you create a complete image of the SD Card with:
rpi ~$ sudo dd if=/dev/sdb of=sdcard.img bs=4M conv=fsync
Then replace the SD Card in the card reader with an empty one and flash it with the ...
As of bump to 4.19.80 the w5500 driver exists, at least for SPI0.
I did a short test with RPi Zero (Buster lite) and everything performed as expected.
Info: Overlay for the Wiznet W5500 Ethernet Controller on SPI0
int_pin: GPIO used for INT (default 25)
speed: SPI bus speed (...
Does the driver exist ?
Yes, there is a driver which was mainlined in version 5.3. Raspbian is currently using version 4.19, so you'll have to wait or build the driver yourself. Running rpi-update is also worth a try, judging by the github they are already testing version 5.5.
Is it possible to add "dtoverlay=w5500" in the config.txt ?
You'll have to ...
I was able to get it working by adding sdio_overclock=25 to the dtoverlay line to set the clock speed to 25mhz. That said, I am not sure if this is specific to the interface on the board, the SD card I was testing with, a Samsung 32GB EVO Select, or the compute module itself but I would have thought this is something that would be auto-detected...
I think there are a couple of options here but like anything else it depends on your use case. To have true simultaneous image capture you would need to have multiple pi’s. There is an interesting product called the cluster hat that will connect up to 4 zeros as a cluster and allows them to be controlled by a single Pi3.
here is a really cool example ...
From the datasheet
The BCM2837 USB port is On-The-Go (OTG) capable. If using either as a fixed slave or fixed master, please tie the USB_OTGID pin to ground.
The USB port (Pins USBDP and USBDM) must be routed as 90 ohm differential PCB traces.
Note that the port is capable of being used as a true OTG port however there is no official documentation....
By "proprietary Board" I'm inferring that you mean an IO board from a third-party- one that doesn't ship with the default compute module kit.
I've flashed both the standard IO board that ships with the compute module as well as a third-party carrier board (IO Board) from Balena (which is REALLY NICE!)using the following procedure that I've previously ...
It's not supposed to be possible, if you look at the specs.
However, I've managed to do something similar, to some degree, with a Raspberry Pi 2/3 and a cheap HDMI to VGA converter. If I power the converter but not the Pi, the Pi seems to boot and/or not power off. The Pi's power LED illuminates, and if the Pi was already powered, stays on. I'm sure an ...
Raspberry Pi 3B has Bluetooth disabled by default. If the Bluetooth is disabled, hcuiart service will fail to start and bluetoothctl will throw an error saying No default controller available
To turn on the Bluetooth, comment following line from
Reboot the Pi after saving the changes and the error should be ...
Instead of using uv4l's raspicam driver to driver the raspberry pi camera, you can use the kernel-based bcm2835-v4l2 driver. Just modprobe it and enable it using raspi-config, and you should have a /dev/video0 file.
After the device file appears, you can start uv4l with these options:
uv4l --external-driver --device-name=video0
The text overlay will be ...
Per the Compute Module's documentation:
Currently the DSI interface is not openly documented and only DSI
displays supported by the official Raspberry Pi firmware will work
with this interface.
I'd suggest taking a look at the official Raspberry Pi display, which should, I think, be supported.
After following the link provided by strumpet, the correct address to stream the video with VLC is
where raspberry is the IP and port is the selected port in the uv4l command (9000 in my case).
SSH has been designed for Shells , for arbitary serial data use Ser2Net instead !
Here is a tutorial on how to use Ser2net to replace serial cables with an IP network :
Note: The Python program controlling the serial port has to run on your Linux desktop now !
For a free Electronics CAD system why not use the GNU Public Licensed GEDA suite! That is as much OSS as anyone wish for - though that does not answer your original question about a pre-designed schematic. One feature that relates to the worthwhile advice of @ppumkin is that when laying up the schematic you can work in "blocks" which you interconnect and ...
