C3 Smart Mini Computing Motherboard

Overview

Powered by the Rockchip RK3288 quad-core Cortex-A17 processor running at up to 1.6GHz, the C3 Smart Mini Computing Motherboard delivers high-performance computing in an ultra-compact 100mm × 72mm form factor. The integrated Mali-T764 GPU supports OpenGL ES 1.1/2.0/3.1 and hardware-accelerated 4K video decoding, making it ideal for 4K digital signage, industrial HMI, smart retail, and embedded vision applications. With 4× TTL/RS-232 compatible serial ports, 9× GPIO, VGA and HDMI 2.0 outputs (supporting up to 4K), plus MiniPCI-E for 4G expansion, this board offers exceptional connectivity for such a small footprint. The onboard RTC with CR1220 battery backup supports scheduled power-on/off, while the 9V–15V wide voltage input ensures stable operation in various power environments. Ships with Android 5.1 (upgradeable to 6.0 or 7.1), with open API SDK available for custom development. Operating temperature range 0°C to 70°C.

Key Advantages

  • 4K Video Processing Power: The Mali-T764 GPU delivers true 4K hardware video decoding, making this mini board perfect for ultra-HD digital signage, video walls, and high-resolution display applications.

  • Ultra-Compact, Space-Saving Design: Measuring just 100mm × 72mm, this mini motherboard fits into tight enclosures while offering the connectivity of a full-size industrial board.

  • Rich Display and Connectivity Options: HDMI 2.0 (4K) + VGA (1080P) dual display outputs enable flexible video solutions. Wide range of I/O—4× serial ports, 9× GPIO, 4× USB 2.0 ports, plus onboard Wi-Fi and Bluetooth support.

  • Flexible Expansion: MiniPCI-E slot for optional 4G module with onboard Nano-SIM card socket, plus self-eject TF card slot supporting up to 128GB external storage.

  • Open for Custom Development: Open API SDK and multiple Android version options (5.1/6.0/7.1) enable rapid application development and deployment across various industries.

Why Choose This Board?

  • 4K Display at Mini Size: Most boards this small can't handle 4K—the C3 delivers it through HDMI 2.0, making it ideal for high-end digital signage and video walls.

  • Built for Industrial Applications: Rockchip RK3288 is a proven industrial-grade processor platform, with operating temperature 0°C–70°C and humidity tolerance up to 95% (non-condensing).

  • Quick Time-to-Market: Ships with Android pre-installed. Open API SDK and comprehensive documentation help developers get products to market faster.

  • Legacy-Friendly: VGA output, RS-232 serial ports, and GPIO support simplify integration with existing industrial equipment—no costly adapters or converters needed.

  • One-Stop Solution: Combines 4K display, connectivity, expansion, and control features on a single board—reduces BOM complexity and simplifies hardware design.
