Rockchip RK3399
A proven big.LITTLE application processor: dual Cortex-A72 performance cores alongside quad Cortex-A53. A long-serving, well-supported platform for signage and HMI where the newer NPU-focused chips are not required.
Boards using it: KTM-S39-II, KTM-S88.

What it means for your product
The RK3399's dual A72 cores give it strong single-thread performance for its generation — good for responsive UI and HMI panels. It handles 4K video and dual display, covering most signage and interactive-kiosk needs.
It has no dedicated NPU in the sense the RK3568/3588 do. For AI-centric products, choose an NPU-equipped chip (RK3568 and up). For general signage, HMI and interactive displays, the RK3399 remains a stable, mature choice with broad software support.
Software
Runs the same firmware and API as every KTM board.
