Product Overview
This product is an AI terminal mainboard based on the Rockchip RK3576 octa-core processor, with a maximum clock speed of 2.2GHz. It integrates a powerful 6 TOPS AI accelerator NPU, supporting hardware acceleration for the latest Transformer-based large AI models and a variety of deep learning frameworks.
The board runs Android 14 by default and also supports Linux and OpenHarmony. It delivers 4K@120Hz ultra-high-definition display output and provides a rich range of expansion interfaces. It is primarily designed for edge computing, AI robots, AI cloud servers, and high-performance edge AIoT devices.
Onboard Interfaces for Industrial Applications
Compared with the RK3288 turnstile mainboard, the RK3576 solution adds high-speed interfaces and enhanced AI camera capabilities:
- Display Output: HDMI 2.1 (4K@120Hz), eDP, LVDS, and MIPI-DSI. Supports three independent displays and can directly drive 7–15-inch touchscreen displays.
- Camera Interfaces: Multiple MIPI-CSI-2 and USB 3.0 interfaces, supporting simultaneous connection of multiple binocular facial recognition cameras.
- Network Connectivity: Dual Gigabit Ethernet ports; Wi-Fi 5 + Bluetooth 5.2; M.2/mini-PCIe interfaces supporting 4G/5G modules.
- Industrial Control: Relay output, Wiegand 26/34, RS485, RS232, CAN-FD, multiple GPIO and ADC interfaces, hardware watchdog, and wide-voltage 9–24V power input. Some configurations support PoE power supply.
- High-Speed Peripherals: USB 3.0, USB 2.0, and PCIe 2.1, with support for external AI accelerator cards.
