What still needs checking
Battery capacity, measured runtime, dimensions and weight remain unverified.
The display implementation describes a software target; physical panel markings and supplied board revision have not been inspected.
Current original-kit availability and packaging variants remain unconfirmed; Codee is a different product.
The anatomy guide describes an LED with a built-in controller; the linked schematic instead shows separate RGB channels. The LED controller type remains unresolved.
