Arduino UNO Q Explanation: Hybrid Board With Linux Computer + Microcontroller Explained for Those Curious About It

Arduino UNO Q Explanation: Hybrid Board With Linux Computer + Microcontroller Explained for Those Curious About It Meta description: Arduino's new UNO Q board is a departure from the usual Arduino board, combining a full Linux computer and a real-time microcontroller on a single board, blurring the lines between an "Arduino project" and a "Raspberry Pi project". Introduction Arduino has released one of their most exciting boards in years, the new UNO Q which aims to bring a full Linux computer and a real-time based microcontroller onto a single board, blending the distinction between "Arduino project" and "Raspberry Pi project". What Makes the UNO Q Different Arduino boards have always been microcontrollers, which is excellent for real-time based hardware projects, but don't offer much in terms of an operating system and processing power for anything more involved than basic logic. The UNO Q board changes this by combining two different p...

Raspberry Pi 500+ Detailed Analysis: Enhanced Keyboard PC Review

Raspberry Pi 500+ Detailed Analysis: Enhanced Keyboard PC Review

Meta description: Raspberry Pi's latest 500+ model offers a mechanical keyboard and 16GB of RAM in a keyboard computer form factor. Here's what's new and who it makes sense for.

Introduction

Raspberry Pi has unveiled an upgraded version of its keyboard-built-in computer product - the Raspberry Pi 500+. This model represents a more serious and powerful take on the concept of the Pi 500 intended for people looking for a genuinely practical daily driver computer as an alternative to using Raspberry Pis as hobbyist boards in enclosed enclosures.

What the Raspberry Pi 500+ Actually Is

Like its predecessors (the Pi 400 and Pi 500) the 500+ is a full computer built into a keyboard - you simply attach a monitor, mouse and power supply to make a fully formed, compact desktop computer.

What's New Compared to the Pi 500

The 500+ offers three main upgrades over the standard Pi 500:

  • 16GB of RAM (compared to 8GB in the standard Pi 500)
  • Upgraded storage in the form of a 256GB NVMe SSD (in an M.2 2280 slot) compared to microSD-only storage in previous models, plus the drive is user-replaceable should you need more space
  • A proper mechanical keyboard (Gateron KS-33 low-profile mechanical switches with removable keycaps and individually addressable RGB lighting) replacing the simple membrane keyboard of earlier models

Full Specifications

  • Processor: Raspberry Pi 5 chipset - quad-core Arm Cortex-A76 @ 2.4GHz
  • RAM: 16GB
  • Storage: 256GB NVMe SSD (M.2 2280 slot, upgradeable)
  • Display output: Dual micro-HDMI ports (supporting 4K)
  • Connectivity: Wi-Fi 5 (802.11ac), Bluetooth 5.0, Gigabit Ethernet
  • USB ports: Two USB 3.0, one USB 2.0
  • Keyboard: Mechanical switches with removable keycaps and per-key RGB lighting
  • Price: Roughly $200 for the keyboard unit with a Desktop Kit (mouse, power supply and HDMI cable) also available for a premium price

Who This Is For

The Pi 500+ is for people looking for a genuinely practical everyday drive computer that takes the keyboard computer form factor to a whole new level of capability in a compact and hobbyist-friendly form factor. It makes the most sense for:

  • Makers who want an always-on dedicated Linux desktop for coding/scripting work as well as general-purpose use
  • People who want a compact secondary computer for terminal use and/or learning Linux
  • Retro-computing enthusiasts who want something that looks like an old home computer from the 1980s

The Pi 500+ is less suited to hardcore GPIO/hardware tinkering projects because the keyboard PC form factor doesn't offer as convenient access to the Raspberry Pi's GPIO header as a standard board would.

Should You Upgrade From the Standard Pi 500?

If you're happy with 8GB of RAM and microSD storage for your purposes, then the standard Pi 500 is a fine alternative that will get the job done and is more affordable. The 500+ makes most sense if you specifically want the faster NVMe storage and extra RAM for heavier use cases, or just want a nicer mechanical keyboard typing experience.

Frequently Asked Questions

Can I still access the GPIO pins on the Raspberry Pi 500+?

Yes - but the keyboard form factor makes accessing the GPIO less convenient than a bare Raspberry Pi 5 board would, so you might want to consider a standard board if your primary use case will be electronics projects.

Does it come with an operating system pre-installed?

Yes, it comes with Raspberry Pi OS pre-installed on the internal NVMe storage.

Can I use a microSD card as well as the internal SSD?

Yes, the microSD card slot is still available alongside the internal NVMe storage, useful if you want a second storage option or want to do alternate OS booting.

Is this a good option for kids/absolute beginners?

It can be, much like earlier Pi keyboard computers, but you might want to consider a standard Raspberry Pi board for an introductory computer if the higher price point is an issue.

Conclusion

The Raspberry Pi 500+ builds upon the keyboard computer concept pioneered by the Pi 400 in a more serious and practical direction - it offers proper storage speed, enough RAM for serious multitasking and a genuinely nice mechanical keyboard experience to fulfill the needs of makers who want a dedicated always-on Linux desktop without the hassle of assembling a separate board and case. However, for projects that specifically involve heavy electronics tinkering, a standard Raspberry Pi 5 board with its convenient GPIO access remains a superior alternative.
