I have never seen a rpi5 available in my life I thought it was just a gaslight.
1GB Raspberry Pi 5
But why? It’s a shame to pair the actually pretty damn good hardware of the Pi 5 with that little (non upgradeable) ram. It’s future landfill fodder. The 1/2gb Pi 4 is better for that low price point.
Yeah and it uses more wattage than the 4.
1gb makes it an easier to program microcontroller.
Why not get an actual micro controller if you want a micro controller? That’s what the pico line is for.
Because Pi programming is extremely easy. My son programmed his Pi in Scratch for the elementary school Science Fair. There’s no way he could have learned C to do it with a real microcontroller.
Look up what Qualcomm is doing to Arduino and you’ll understand why RPi is motioning themselves this way
How?
You can use Scratch, the drag and drop flowchart programming language for young children to read and write to the gpio ports. My son did an elementary school science fair project with it.
A few years later I pulled out the same Pi and used it with Scratch to make a temporary cat litter box alarm when I needed a urine sample for the vet. I use esp32s for my projects but using the Pi took minutes instead of hours program.
Can’t you do all that with a 4 or 8GB version?
Yes for more money. Why buy an 8GB Pi5 instead of a 16GB?
What? You said it having 1GB of memory makes it an easier to program microcontroller. I’m just trying to figure out how that makes sense. The amount of memory doesn’t matter when programming it.
A typical microcontroller like a Raspberry Pico ESP32, or Arduino has 520K of RAM. Not Megabytes but Kilobytes. There’s no OS. There are no drivers. There’s no sound or video output. You run a development environment on your pc, it compiles the code to byte code and then you transfer that data to the rom built into the microcontroller using the development environment because in most cases the Microcontroller flash isn’t visible to Windows/Mac/Linux as a fat drive.
Using a 1GB Pi as a microcontroller means you boot Linux, run Scratch/Python, C, type your code, and test it dynamically. You have video and audio out available. You are running a single simple program that would otherwise run on a 200 Mhz CPU with 520k ram. So a 2.4Ghz Pi with 1 Gigabyte ram is gigantic in comparison making development much easier.
What most pi’s get used for.
Theres a store page, but that doesn’t make it available.
