Short answer: yes, maybe. You probably want a 4 GB system, as at least it can act as a lightweight desktop(-ish) system if the controller project doesn't work out. Also, read the bit about Imager below, as it makes setting up a Raspberry Pi trivial. --------- Longer answer: It should do. Check availability, though; Elmwood seems to be short of Raspberry Pi 4 kits, so they may be back-ordered from Canakit too. Buyapi (in Nepean) and Canakit are Canadian official resellers, so are supposed to get priority on stock. Practically, they'll run out like everyone else from time to time. Choice of OS could be critical: Raspberry Pi OS (the OS formerly known as Raspbian) is a 32-bit Debian-derived distro. Ubuntu is 64-bit. Raspberry Pi OS has devices and drivers tweaked to work with the Raspberry Pi's hardware, as well as support from the Raspberry Pi Foundation. Ubuntu may not have all the best and brightest drivers, and Raspberry Pi-specific support may be lacking. For installation, you'll probably want to replace whatever comes on the supplied SD card with a known latest release. Many Raspberry Pi SD cards still come installed with a slightly annoying (but super quick for vendors to install) distro wrapper called NOOBS. Raspberry Pi Imager is probably the quickest way to install an OS on the card: https://www.raspberrypi.org/software/ You might want to install Raspberry Pi OS Lite, which doesn't run a desktop. Imager has a 'secret' setup screen (Ctrl + Shift + X) that allows you to pre-configure bits of your system, such as user password, ssh keys and wifi access (if you need it). Details: https://www.raspberrypi.org/blog/raspberry-pi-imager-update-to-v1-6/ Regarding running the Unifi controller, it looks like it's a bit of a hack to get it running. Both tutorials I found recommend adding Ubiquiti's Debian repo to the system. On a Raspberry Pi, this can result in anything from "zero problems" to "everything stops working, forever". It all depends what the repo pulls in and assumes about the system. Both tutorials aren't perfect, but are a start: 1) https://pimylifeup.com/rasberry-pi-unifi/ 2) https://lazyadmin.nl/home-network/installing-unifi-controller-on-a-raspberry-pi-in-5-min/ In particular, both recommend unnecessary messing with the system entropy source. If you install rng-tools (sudo apt install rng-tools) without messing with the config file, it will automatically pull in the hardware entropy source. It looks like both of these followed old advice. 'Old', in the Raspberry Pi world, is anything older than 18 months or so. So much changes with the Raspberry Pi hardware and software that old advice can sometimes be detrimental. cheers, Stewart --- Post to this mailing list talk@gtalug.org Unsubscribe from this mailing list https://gtalug.org/mailman/listinfo/talk
