Seen on YouTube, a first-generation iPod touch prototype.
It’s a (large) board that is literally the iPod touch motherboard, with connectors to help debug potential issues. In the video, we learn that it only boots in DFU mode, mainly because the storage is missing. Also, the CPU dates back significantly before the device’s release.
The board
It’s just a screen
Two dock connectors
Analog video outputs
A mini USB port, quite uncommon
Here, there should be slots with NAND storage
Under the screen
In the middle, there’s the CPU and probably traces for NAND storage.
