Welcome to the programming.dev Raspberry Pi community!

Raspberry Pi is a series of small single-board computers. It is widely used in many areas because of its low cost, modularity, and open design. It is typically used by computer and electronic hobbyists.

go replan all your STM32H7 projects with RP2350, save money, headaches, and time. As a bonus, you’ll get an extra core to play with too! "But," you might say, "STMicro chips come with internal flash, while RP2350 still requires an external SPI chip to store the flash". Hold on to your hats... there are now RP2350 variants with built-in flash! They are called RP2354A nd RP2354B and they include 2MBytes of flash in-package. The pinouts are the same as the RP2350A/B, for a bonus! Why two pinouts? Because the "more GPIOs" dream also came true! There is now a variant with more GPIOS, available in an 80-pin package. That’s right! It is epic!

We’re happy to announce the launch of Raspberry Pi Pico 2, our second-generation microcontroller board, built on RP2350: a new high-performance, secure microcontroller designed here at Raspberry Pi.

With a higher core clock speed, twice the memory, more powerful Arm cores, new security features, and upgraded interfacing capabilities, Pico 2 delivers a significant performance and feature uplift, while retaining hardware and software compatibility with earlier members of the Pico series.

Pico 2 is on sale now, priced at $5.

Why do the vast majority of these seem to either block off the 40pin header or convert it to female header that's incompatible with further hats? And why are they full sized, despite having minimal circuitry on them? I can appreciate the ones that build in a cooling system, but that doesn't need to block off all the pins that aren't being used by the hat.

It seems like all this could be accomplished with a small board that doesn't interfere with everything else one intends to do with a Pi or Pi-clone. In fact, I'm surprised at the lack of built-in POE Pi boards out there.

i kinda wanna buy one to toss it in my backpack with a 2TB ssd full of movies and stuff to have a zero latency netflix anywhere i go.

im just a little bit confused because jellyfin docs say that its not a good idea at all to run it on a raspberry pi (or any other single board computer), so i thought i'd ask here if anyone has done that. i mean, just one user shouldn't be that much for a raspberry pi, right?

"Raspberry Pi Ltd, a leader in low-cost, high-performance computing, announces that it is considering an initial public offering (the "IPO" or the "Offer") and that it intends to publish today a registration document (the "Registration Document"). The Company is considering applying for admission of its ordinary shares to the premium listing segment of the Official List of the FCA and to trading on the Main Market of the London Stock Exchange ("Admission")."

I have a Keybow MINI hooked up to a Raspberry Pi Zero W, and I'm using Python to respond to events. I have one button that kicks off playing a song on a passive buzzer, and I'm wondering if there's a way to have a button press stop the song before it completes.

I want to build my own portable E-Reader like a Tolino/Kindle in DIN-A5 format (I know there are similar projects, like the Open Book from joeycastillo, but I want to make my own just for fun). I'm considering using the Compute Module 4 from Raspberry Pi. That, at least according to my theories, would have the advantage of me not needing to create my own OS, and the availability of already existing EPUB/HTML (EPUB is essentially just HTML) & PDF parsers and UI libraries hopefully makes my life easier. I don't want to use a default Raspberry Pi, because I don't need all the ports and I want the size of the E-Reader to be not unnecessarily thick.

The modules I need/want:

  • Micro SD Card Reader for internal Storage (or just using eMMC Storage, have not settled yet on that topic)
  • SD Card Reader (large/normal sized SD Cards), with a snap-in/spring mechanism (like with Nintendo (3)DS cartridges)
  • E-Paper Display (e.g. a waveshare)
  • USB-C Port for charging the battery (and maybe, if possible also file transfer and if possible maybe also to connect to a docking station)
  • Battery

What is your experience with the Compute Module (4) and do you have good resources for creating my own PCB extension module for the Compute Module you would like to share? Do you have constructive critique for my project idea?

Hi, question for the group.

I have a pi zero 2 running the lite OS suggested by the imager. I’ve been able to create a RAID with 2 240gb SSD on the usb port. Even during a peak read/write stress test, the power draw for the whole system doesn’t exceed 800ma.

Anyhow, ideally I would like to boot from this volume and elimante the SD card completely, but have been stopped by not even being able to boot with the root set to the RAID and the boot dir still on an SD. I can get it to boot when /usr and / var are on the raid

Has anyone any insights on different things to try? Perhaps even a good reason this can’t work would free me from this fools quest so my project can advance?
