Sprout is a forthcoming drop-in motherboard for selected monochrome iPods. It keeps the donor player’s enclosure, clickwheel, display and controls while adding Bluetooth audio, Wi‑Fi, USB‑C, a modern DAC and SD-card storage of up to 2TB. A Pico version is designed mainly for offline playback; a Pi version adds Linux, streaming and apps. Spotify and Apple Music are currently only working proofs of concept, not permanent service guarantees.
What Sprout changes—and what it keeps
The project replaces the original motherboard rather than modifying the iPod’s exterior. The maker describes the installation as requiring no soldering and being fully reversible. The original shell, clickwheel, screen and other user-facing parts are reused. The battery and hard drive are the stated exceptions: each build needs a compatible battery, and storage moves to an SD card rather than the donor’s original hard disk.
That design addresses several common classic-iPod upgrades at once. Bluetooth enables wireless headphones, Wi‑Fi provides network connectivity, USB‑C handles charging and data, and the 3.5mm jack receives output from a Hi‑Fi DAC identified as CS43131 or a similar part. The board also exposes two GPIO pins through the original remote connector for future hardware or accessory projects.
Which iPods are compatible?
The official compatibility list is limited to these monochrome models:

A 5th-, 6th- or 7th-generation iPod is not listed and should not be purchased as a presumed donor. Check the generation and physical model before buying a used unit; “classic iPod” is not specific enough to establish compatibility.
Pico versus Pi
Both boards share the core audio and connectivity features, but they target different uses. Sprout Pico uses a Raspberry Pi RP2350 and is intended as the simpler, lower-power offline player. Sprout Pi adds a Raspberry Pi Compute Module Zero, creating a Linux-based environment for streaming, AirPlay and custom applications.

Streaming should be treated as experimental at launch. The maker labels Spotify and Apple Music “working proofs of concept as of September 2026” and warns that service APIs change frequently. An integration that works on a prototype can therefore stop working or require updates after release.
Rank #3

| iPod mini | 1,200mAh | 20 hours |
The author specifies a standard 3.7V LiPo battery with a JST PH 2.0mm connector. Exact battery dimensions, connector polarity and clearance inside the enclosure still need to be checked for each donor and battery combination. Do not assume that a battery with the right capacity will physically fit or that its wiring is safe without verifying polarity.
Recommended Free Tools
Practical preparation checklist
- Confirm that the donor is a listed 3G, 4G or 1st/2nd-generation mini model.
- Inspect the shell, clickwheel, display and 3.5mm jack for damage before disassembly.
- Measure the replacement battery and verify 3.7V rating, JST PH 2.0mm connector, polarity and internal clearance.
- Plan for a microSD card; the documented ceiling is up to 2TB.
- Have a USB‑C cable available for charging, data transfer and digital-audio use.
How the installation is expected to work
Sprout is intended as a board swap rather than a soldering project. The exact assembly guide and production hardware should be followed when released, but the documented workflow is:
Best Value

- Power down and open the compatible donor iPod, preserving the enclosure and user-facing parts.
- Remove the original motherboard and hard-drive assembly as directed by the final build guide.
- Install the Sprout board in the original housing and reconnect the clickwheel, display and other retained parts.
- Fit the verified 3.7V LiPo battery and JST PH 2.0mm connector, checking polarity before power is applied.
- Insert and prepare an SD card, staying within the stated 2TB maximum.
- Close the enclosure, connect USB‑C for charging or data, and pair Bluetooth headphones through the software.
Because the maker calls the process reversible and solder-free, the 30-pin connector is not being manually rewired. USB‑C is provided by the replacement board. The final mechanical fit and cable routing still depend on the specific donor model and production instructions.
Using Bluetooth headphones, including AirPods
Bluetooth audio is listed for both variants, so compatible wireless headphones and earbuds are a central use case. AirPods use Bluetooth audio and should be usable if the finished firmware supports their standard pairing behavior, although the project materials do not document model-by-model AirPods testing. The original 3.5mm jack remains useful for wired headphones and for the board’s DAC output.
Availability, price and launch status
Sprout is an upcoming hardware project, not a verified retail product. The project announcement says launch is planned through Crowd Supply, while the official page asks readers to sign up for updates. TechSpot reported on October 15, 2026 that pricing was not yet available. No confirmed retail price, shipping date or production review has been published in the available material.
That status matters when choosing a donor or buying parts now: compatibility is documented, but final board availability, software support and streaming reliability remain subject to the launch hardware and future service changes.
Quick Recap
Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon at the time of purchase will apply.
