Thanks Lee for the information, bout a year ago I wanted to buy a CM4 to power a Raspberry PI laptop kit that just came out but ended up buying a PINE BOOK PRO after the 8 month wait list at the price of a PINE BOOK PRO.
Good to see the shortage ending, but by the time I would get one they will have released the CM5 module, or as I always say: "If it were not for bad luck, I's have no luck at all"....:)!
Have a nice day!
That sounds to me like the lyrics of "Born Under A Bad Sign" by Albert King - in which case I salute your good musical taste!
I love the Raspberry Pi 4 Compute Modules. I have 2 modules, one that I put in a GPi2 and one that I have for testing as a micro-server. The problem is that I got mine through an electronics supplier right as the supply problems took hold. Even if my testing of the CM4 went well, I wasn't able to get more. (And I did try.) I honestly would be deploying a cluster of these if RPi could have kept them available.
Now we have the Orange Pi 5 and 5 Plus. These boards are so good out of the box that the ability to reassign the usage of the PCIe lane by swapping carrier boards on the CM4 just isn't competitive. It's cheaper and easier for me to purchase more OPi5 boards. And I can get so much more memory and performance out of the OPi5 boards over the CM4.
I've never tried Kali, but that's a really cool feature for obscuring what you're doing. If I ever fix up the old laptop I'll have to copy that over to Slackware.
Kali's a great tool for cyber-security and I'd never discourage anyone from firing it up to have a play on their own network (or one where they have permission to run it) because you can learn a lot very quickly.
It sounds like you're planning of running it in a VM on Slackware which is the best way to use Kali - I've seen some people try to use it as a desktop OS and it's just designed for that in any shape or form.
@@terrydaktyllus1320there is a built in option to “tweak” Kali so that’s it’s useable as an everyday OS. “Hardened mode”
Kali is awesome
Whaaaat! Kali thumbnail! 😅😊
I remember suggesting trying Kali years ago!
For what it is, it's not bad. When o add the cost to the CM4 module, then it may not quite have the same appeal of value.
If I don't need GPIO pins, which is the case for most of my projects, then I find it very difficult to justify buying a Pi or any kind of SBC when, for example, just yesterday I picked up a used Dell Optiplex 3020 SFF PC with a 4th generation i3 processor and 4GB RAM for £20 including postage - and that was a "Buy It Now", not me spending a lot of time waiting for an auction bargain to appear.
I love to try that board with a Banana-Pi CM4
Interesting: would that even work?
@@SchoolforHackers yes BPi CM4 do work with Raspberry Pi boards, I have a Wave Share Board that I am running my BPi on, that is mean for Raspberry Pi.
What a lovely thing
Are you going to try it with the new opi cm4?
Cytron doesn't make an enclosure for this beastie, is there a third party option? I would like to take it to the field but would prefer it not be naked when I do because it might be damaged.
I haven’t seen one
Thats a really cool board for a CM4 module. 👍
Interesting video and a great little board, although i don't see how your getting 1Gb ethernet and an NVME interface at the same time as the board only support USB 2.0 which only support something like 350mbs🤔
No problem at all. The Gigabit Ethernet is directly from CM4 Ethernet interface (not going through the PCIe bus), while the USB2.0 is directly from CM4's USB 2.0 interface. The PCIe Gen 2 x 1 lane of CM4 is reserved for M.2 socket.
🙋
Can it be powered from batteries via GPIO?
It’s not something I have tried
@@leepspvideo If you wanted to be build a laptop or a TRS80 Model-100-look-alike. this is the sort of board you would use I think. It is just a shame that manufacturers don't put an alternative 'power in' on the opposite from the main block ports. If you get my drift.
@@clangerbasher Why would you waste such resources just to emulate a TRS-80? Some clever people have already got ZX Spectrum emulators running on ESP-32 and Pi Pico micro-controller boards - you're only emulating a Z80 CPU running at 3.5 MHz after all.
@@terrydaktyllus1320 Go read what I said and then get back to me.
That speed on the maker board is NOT what you should be getting... you SHOULD be getting pci-e 2.0 x4 speed (which I THINK would be a little over 1GB/s at it's fastest) .... but you seen to be getting the USB 3.0 speeds..
- I COULD BE WRONG THO..... I honestly never did any speed tests when I had my CM4 up and running, but now I'm quite intrigued... but to getting it up and running I would have to erase the SD card in either my phone or my steam deck ( I have misplaced one of my SD cards :( )
- It's still faster I guess, but not the speed that I would expect to get.... OHHHHH maybe it's the nvme m.2 card!!! Is it a SATA card??? I'll bet that it is!!! That's why it's topping out around 300MB/s ..... now it makes sense!!! Yea, you're gonna get the same results until you use an PCI-E nvme m.2 - check to see if it is a B-Key drive .... they are the SATA drives ... you need an M-Key drive for ity to be PCI-E and get the full speed
I could be wrong about this tho... but I've always understood SATA to max out at about 350MB/s which ABOUT what you getting ( in sequential write speed)
I REALLY hope you have a pci-e nvme drive.. I wanna see what that maker board can do... It is IMPRESSIVE!!!! I'd take that over my waveshare any day!! lol (unless it doesn't do pci-e nvme speeds)
This is what I was using
www.cytron.io/p-nvme-2242-b-plus-m-key-makerdisk-ssd-128gb-preloaded-rpi-os
hrmmm.... after looking closely at the Maker Board it says it's M-key so the Maker board SHOULD up to pci-e m.2 cards .... but that means it's all down to what type of m.2 card that is....
- BUT I think even if it the SLOWEST POSSIBLE m.2 card then it SHOULD still be getting HIGHER SPEED than the roughly 300MB/s that you're showing..... BUT maybe that's all that the Raspberry Pi 4 can do, whether it's a 4B or a CM4 .... but I was under the impression the CM4 was much faster than that....
- - I guess the ONLY way I will know FOR SURE is if I put mine back together and run the same test as you.... so until then I'll just stfu about it lol sry :)
@@Nobe_Oddy The NVMe SSD speed was limited by the CM4 PCIe bus. CM4 comes with PCIe Gen 2 x 1 lane only, not 4 lane. That limits the speed.
