With Raspberry Pi boards continuing to be relatively scarce, I've been trying a few alternatives to see what may be usable and good. I had previously written about the Jetson Nano 2GB, which is great, but a little pricey, so I'm trying to find sub-US$100 boards that will run Reactor.
I've got four that I'm trying now, but one in particular goes right to work in the most predictable way and seems worth a mention immediately: the Libre Computer Board AML-S905X-CC 2GB (known as "Le Potato").
The form factor is very similar to that of the Raspberry Pi 3 B+, and has comparable CPU (ARM Cortex-A53, quad 64-bit cores at 1.5+GHz -- slightly higher clock speed). It's US$35 on Amazon and LoverPi in the (recommended) 2GB configuration, and easy to get.
Startup is like RPi: download one of the available OS images (Ubuntu, Raspbian, Debian, ARMbian, etc.) from their site and write the image to a MicroSD card, insert into slot, power up, and off you go. I tried the Ubuntu 22.04 image first and it comes right up. No problem getting nodejs 18.12.1 installed and running (with Reactor).
No WiFi on board, but I don't see that as a minus for use as a controller/hub (which should be hard-wired, IMO). The 40-pin GPIO connector is compatible with typical RPi HATs (PoE, breakouts, etc.).
There is an available eMMC (solid state storage) module to use instead of MicroSD, which I would recommend for long-term use. It runs US$25 for 32GB (64GB and 128GB available). The module is scarcely larger than the chip it carries, and has the smallest board-to-board connector I've ever seen.
Next up: ESPRESSObin 2GB (spoiler: it's... technical...)
Just to start a new thread...
I received last week some kit (3) from Gazouta:techGazouta Technologies / Jul 14, 2018 Professional Wall Mount for Raspberry Pi Touchscreen (Black Anodized Aluminum) | Gazouta Technologies Professional Wall Mount for Raspberry Pi Touchscreen (Black Anodized Aluminum) | Gazouta Technologies
This kit will allow you to install a Raspberry Pi Computer and an Official Raspberry Pi 7" Touchscreen as a wall mounted touch controller.
I will work on that in the incoming days/week, the goal it's to put at least one in the main entrance to "replace" the alarm keyboard and they other one in the master bedroom to control "scene".
Will need to figure out some dashboard for that and will probably check also to send some IP camera feed too!
With the price of these little buggers dropping, I am finding more and more the nVidia Jetson nano attractive as a self contained platform to run openLuup/z-way/Home Assistant and all the HomeKit/Alexa bridges of course with a couple of sticks for zigbee and zwave. Because of the included GPU, it can do faster video processing and be a development platform for further ventures into AI and a potential alternative to the rPi4... Enticing for <$100?
Im very frustrated with my new pi. I have 2 pis running on ssds with no sd card great. But for the life of me I can’t get it to boot from the exact same model of ssd that works on my other pi. I also can’t get the new pi to boot from old known working sd card. I tried burning new image onto ssd, known working image, in fact the only way it will boot is with the noobs card it came with. I thought pi3s didn’t have any firmware it was all software, but thats all I can think of. I am stumped. No, I don’t want to boot off sd card. Is it a bad pi? I did every single step multiple times. I know how to do this, ive done it twice. What’s going on?
Any reason why I shouldn’t repurpose a RPi 2 that I have laying around do run openLuup? I know a lot of people seem to be using v3.

I don't see why not. Note that there are two revs of the rPi2. The old one is much slower (about equivalent to the eZLO plus) than the newer one but openLuup should run just fine on either.

Yes, speed is not an issue, or anything else, really. I had openLuup running quite happily on a much-loved Arduino Yun board (Arduino + SOC running OpenWRT.) Ran all my stuff perfectly for many months. If you've seen any of the graphs of CPU / memory, you'll see it's a very small load. A basic openLuup system uses less resources than a single plugin on Vera.
Thanks guys I’ll give it a shot.
