Lenovo Open Source Keyboard — Proprietary Cable Connectivity, Enterprise Keyboard | Open firmware, Wired

Accelerate security reviews and firmware validation with an open-source Lenovo keyboard engineered for managed IT estates. This model exposes keyboard firmware for inspection, reduces black-box risk, and ships with a proprietary cable interface to enforce Lenovo-approved cabling and accessory compatibility. Intended for environments that require documented firmware provenance and controlled physical interfaces, it helps procurement teams standardize on a keyboard that supports internal review processes without introducing unsupported third-party wiring.
