The cost of DRAM remains a relevant factor when selecting hardware for embedded and computing applications. In response to this, Raspberry Pi Official Magazine has presented a range of project concepts that demonstrate how the 1GB variant of Raspberry Pi 5 can be effectively utilized, even in scenarios requiring solid processing performance.
This article is part of a broader discussion focused on optimizing memory usage and selecting the appropriate hardware configuration for specific applications.
Performance without excessive memory requirements
The 1GB version of Raspberry Pi 5 is based on the same BCM2712 system-on-chip (SoC) as higher-memory variants, ensuring identical processing capabilities. This makes it a cost-efficient option for users who require computational performance and advanced interfaces, such as PCIe connectivity for expansion modules (e.g. NVMe SSD storage or AI accelerators like the AI HAT+).
The following project examples highlight practical use cases where the available processing power can be fully leveraged, while keeping memory requirements to a minimum.
Media centre / NAS applications
The presence of a PCIe interface in the 1GB Raspberry Pi 5 significantly expands its storage capabilities. By using a Raspberry Pi M.2 HAT+ (or a compatible alternative), the device can be equipped with an M.2 NVMe SSD, enabling both increased storage capacity and improved data access performance.
In addition, the system can be configured to boot directly from the SSD, eliminating the limitations associated with standard microSD cards, particularly in terms of durability and transfer speeds.
The use of NVMe storage results in a noticeable improvement in read/write performance, which directly translates into faster system response and smoother operation. This makes the platform well suited for applications such as:
- a media centre, supporting streaming of video and audio content,
- a NAS (network-attached storage) solution for centralized data storage and sharing within a local network
These use cases demonstrate that even the 1GB variant can effectively handle storage-intensive tasks when paired with appropriate external hardware.
The simplest way to configure a media centre on Raspberry Pi 5 is by using a Kodi-based operating system, such as LibreELEC or OSMC. These solutions provide a ready-to-use environment optimized for multimedia playback, minimizing the need for manual configuration.
As an alternative, the device can be deployed as a dedicated NAS unit. In this configuration, files stored on the system can be shared with other devices within the network using the Samba protocol, enabling convenient wireless access from computers, smartphones, or other endpoints.
Both approaches offer practical ways to leverage the available performance of the 1GB Raspberry Pi 5 in typical home or small-scale network environments.
Retro gaming applications
The 1GB Raspberry Pi 5 is also well suited for retro gaming applications, offering sufficient performance to emulate a wide range of classic systems. Increased RAM capacity becomes relevant mainly when targeting newer platforms, while older generations — including PlayStation 1, Sega Saturn, and Dreamcast — can be handled effectively with the 1GB configuration.
This also covers earlier systems such as NES, SNES, Mega Drive/Genesis, Game Boy Advance, MAME arcade machines, ZX Spectrum, Commodore 64, and Amiga, making the platform a versatile base for retro gaming environments.
Software environment and configuration
Several dedicated operating systems are available for this purpose, including Recalbox, Lakka, and Batocera, all of which provide preconfigured environments optimized for emulation. RetroPie is also compatible, although it currently requires manual installation within Raspberry Pi OS, as no dedicated image is available for Raspberry Pi 5.
Game ROMs can be transferred to the device via USB storage or over the local network, depending on the selected setup.
Legal considerations
When sourcing ROM files, it is important to ensure compliance with applicable copyright regulations. Downloading content from unauthorized sources may violate intellectual property rights.
At the same time, a wide range of legal ROMs is available, including public domain titles and modern homebrew games developed specifically for classic hardware platforms.
This type of application demonstrates that even with limited memory, Raspberry Pi 5 can deliver a fully functional and flexible retro gaming system.
Internet radio and hi-fi applications
Although the 1GB Raspberry Pi 5 does not feature a dedicated analog audio output, it can still be effectively used in audio playback applications. Sound can be transmitted via Bluetooth (to headphones or speakers) or through HDMI, for example when connected to a TV or AV receiver.
For applications requiring higher audio quality, the platform can be extended with dedicated DAC HAT modules, enabling integration with hi-fi systems. Solutions such as the Raspberry Pi DAC Pro support high-resolution audio playback up to 24-bit / 192 kHz, significantly exceeding the parameters of standard CD-quality audio (16-bit / 44.1 kHz).
Software ecosystem and functionality
A wide range of software solutions is available for audio playback on Raspberry Pi, including specialized operating systems such as Volumio, moOde, and piCorePlayer. These platforms provide ready-to-use environments for managing music libraries and streaming content.
Depending on the configuration, users can access:
- locally stored audio files,
- popular streaming services,
- internet radio stations
In addition, many solutions support multi-room audio, allowing synchronized playback across multiple network-connected devices.
System integration and design
Raspberry Pi-based audio systems can be easily adapted to different use cases, from simple internet radios to more advanced hi-fi setups. The compact form factor of the device also allows for flexible enclosure design — for example, integration into custom housings or retro-style audio equipment.
Magic mirror
The magic mirror is one of the most recognizable Raspberry Pi projects, combining display functionality with real-time data presentation. The system can be used to show information such as weather forecasts, news feeds, traffic updates, or calendar events, making it a practical addition to smart home environments.
Hardware setup
Building a magic mirror does not require complex components. The basic setup includes:
- a display (TV or monitor),
- a two-way mirror panel (glass or film applied to standard glass),
- a suitable enclosure or frame
The frame can be sourced as a ready-made solution or constructed independently, depending on the level of customization required.
Software and configuration
The software layer is typically based on the MagicMirror² platform, available at magicmirror.builders. The project offers extensive documentation and a wide range of modules, enabling users to expand functionality according to specific needs.
The system requires the desktop version of Raspberry Pi OS, as it relies on a graphical environment for content presentation.
Application context
The 1GB Raspberry Pi 5 provides sufficient performance for this type of application, as the workload is primarily focused on data visualization and lightweight processing, rather than memory-intensive operations.
