[Interest Check] Thinking about designing a modern, custom drop-in replacement motherboard for the iPod 5G (RP2350, Native Rockbox, Integrated BT) – Anyone interested?
Hey everyone,
I’m a 17-year-old hardware hobbyist and absolutely love the iPod Classic 5G (Video). Lately, I’ve had this project stuck in my head, and before I actually spend my budget on parts and start prototyping, I wanted to do some quick market research and get some feedback from you guys.
We all love the 5G, but original motherboards are getting old, dying, or are just way too expensive on eBay right now. Plus, internal Bluetooth mods usually involve janky soldering, and 30-pin transmitters are just bulky.
So, I’m seriously considering designing a completely custom, modern drop-in replacement motherboard for the iPod 5G from scratch using KiCad.
Here’s what I’m planning so far:
It will fit perfectly into the original 5G thin or thick backcovers without any case modding.
Powered by a modern, cheap microcontroller like the new Raspberry Pi RP2350 (or RP2040).
Native Rockbox: This is the main goal. No modern Android/touchscreen OS. It should run Bare-Metal Rockbox by mapping the hardware pins correctly. So it will look, feel, and control exactly like a stock iPod running Rockbox, meaning full support for all community themes and the original clickwheel.
Integrated Bluetooth: Fully controllable directly inside the Rockbox settings menu (no external pairing buttons or cutting holes into the case).
Good Audio: A dedicated, high-end Audio DAC (like Texas Instruments or Cirrus Logic) so the 3.5mm jack keeps that legendary sound quality.
Storage: Just a MicroSD slot directly on the board.
DIY-Friendly: I want to use standard, readable SMD components (0805 or 0603) so people with a basic hot-air station can actually repair or mod the board themselves if something breaks.
Just to be 100% clear: I haven’t started building it yet. Right now, I’m just mapping out the schematics and checking if everything is feasible. Before I order individual AliExpress connectors, FPC breakout boards, and test chips, I want to see if people actually want this.
If I can get a prototype working on my desk, my plan is to do a small pre-order run of professionally assembled PCBs (via JLCPCB) to keep the price low for everyone. I’d target around €50 per board, which I hope sounds fair.
I’d love to hear your thoughts:
- Would you actually buy a drop-in board like this to revive a dead 5G?
- What features are an absolute must-have for you? Anything special you'd want on a modern board?
- Any technical advice or good documentation on the clickwheel/LCD protocols?
Let me know what you think!
