The Sprout project introduces open-source replacement motherboards for vintage iPods, bringing modern features like Bluetooth, Wi-Fi, HiFi DAC, and USB-C audio without requiring soldering.
It supports multiple classic models, utilizing microSD storage and offering a Linux-powered version built on a Raspberry Pi Compute Module Zero for running custom apps.
The project, called Sprout, offers a new mainboard that replaces the factory one in older iPod models. The process is fully reversible, as the device continues to use its original components, such as the screen, outer case, and signature navigation wheel.
What changes in the interior and capabilities
Installing the new board adds features that weren't there originally, such as Bluetooth wireless headphone connectivity, Wi-Fi, a USB-C port for audio and charging, and the ability to play music via AirPlay. Because the original storage is removed with the old board, songs are now stored on a microSD memory card.
Sprout comes in two different versions:
- Sprout Pico: The basic version of the device.
- Sprout Pi: The advanced version, which features a built-in small computer for access to well-known music streaming services, such as Spotify and Apple Music, as well as the ability to install additional applications.
The user interface remains faithful to the classic menu of old iPods, while adding new features. Among other things, it includes better management for podcasts, displaying album covers even on devices that originally did not have a color screen, as well as the revival of old games.
