2.1 Introduction

SBC-C31 is a Single Board Computer in 3.5" form factor (which is 146 x 102mm) based on embedded Rockchip RK3399 processor, featuring Dual-core ARM

Cortex

-A72 MPCore processor and Quad-core ARM Cortex

multimedia capabilities.

Graphics features of the board are managed directly by Rockchip RK3399 processor, which integrate a 4-Core Mali-T860MP4 GPU, supporting OpenGL ES

1.1/2.0/3.0/3.1, OpenVG 1.1, OpenCL, DirectX11.1.

HW video decoding of the most common coding standard (i.e., H.265 10-bit, H.264 10-bit, VP9 8-bit, MPEG-4, MPEG-2, VP8 and others) is supported. Also

H.264, VP8 encoding is supported.

The board is completed with up to 4GB LPDDR4 64-bit bus memory directly soldered on board and one eMMC 5.1 Flash Drive with up to 64GB of capacity. Mass

storage capabilities are completed by a microSD Card slot.

The board can support 24 bit Single/Dual Channel LVDS interface, one eDP interface, one HDMI standard interface for HDMI1.4 / 2.0a compliant displays and one

DP 1.2 interface on USB Type-C connector (alternate mode).

The processor offers an RGMII interface which, through a dedicated TI DP83867 Ethernet Transceiver, allows the implementation of a Gigabit Ethernet interface.

Another additional GbE interface (optional) is possible using an Intel

The networking capabilities of this module are extended by an optional WiFi 802.11 a/b/g/n/ac + BT 5.0 NGFF module soldered on-board.

An LTE Cat4 module, Quectel EG-25, with dedicated micro-SIM slot is also available as a factory option

The SBC-C31 board offers two USB 3.0, one on standard Type-C connector and one on standard Type-A connector, two USB 2.0 on standard Dual Type-A

connector, an internal header with up to two additional USB 2.0 Host ports (one of this is shared with the optional modem).

The audio functionalities of this board are realised by an I2S audio codec, which manages Line out and Mic In interfaces on a combo TRRS audio jack.

Two internal connectors extend the functionalities of this board. On these connectors, managed as factory options, it is possible to found up to 2x RS-232 or RS-

485 or 4xGPIOs + 1x RS-232, plus given by default 3x GPIOs, 1x Open-Drain Output, 1x I2C and 1x PWM.

The features on SBC-C31 are completed , as factory options, by 1x CAN or SPI flash on-board or SPI external interface, plus by 1x CAN or Ultra Low Power RTC

on-board. Last but not least, SBC-C31 can offer up to two MIPI CSI serial camera interfaces.

The board is available both in commercial and extended temperature range.

Please refer to following chapter for a complete list of all peripherals integrated and characteristics.

SBC-C31

-A53 MPCore processor, with frequencies up to 1.8GHz, which are ideal for applications requiring

I210 Gigabit Ethernet controller, managed through the processor's PCI-e interface.
