Supporting multiple
operating systems

Quad-core RK3506

Equipped with Rockchip's latest industrial-grade chip RK3506, featuring a 22nm advanced process technology,
it integrates a tri-core ARM Cortex-A7 with a single-core Cortex-M0, operating at a speed of up to 1.6GHz.

Low latency, high real-time performance

Supports AMP (Asynchronous Multi-Processing) heterogeneous multi-core architecture, where a single chip can support flexible combinations of Linux, RTOS,
and Bare-metal, such as 2×Cortex-A7 Linux + 1×Cortex-A7 RTOS + Cortex-M0 HAL or 3×Cortex-A7 RTOS + Cortex-M0 HAL,
using the standard RPMsg inter-core communication mechanism.

Adapting to a lightweight
UI framework

The RK3506 SDK natively supports the LVGL lightweight UI framework and,
combined with the chip's internal 2D hardware acceleration,
makes LVGL run more smoothly. The entire chain from hardware
power-up to bootloader loading and kernel loading,
and finally to UI display, is optimized for startup.

Compact size, high performance

Utilizing stamp-hole interfaces, data transmission and expansion capabilities are
optimized for the best performance. The compact design saves valuable space.
High-quality components ensure stable operation, making it suitable for a variety of
industrial products.
