2.1 Introduction
SBC-D23 is a Single Board Computer in 3.5" form factor (which is 146 x 102mm) based on embedded Rockchip PX30 Processor, featuring Quad-Core ARM
®
Cortex
-A35 processor
Graphics features of the board are managed directly by the processor, which integrates a Mali-G31 GPU with High performance dedicated 2D processor, supporting
®
OpenGL
ES 1.1 / 2.0 / 3.2, Vulkan 1.0, OpenCL 2.0 and Open VG 1.1.
HW video decoding of the most common coding standard (i.e., MPEG-4, H.265/HEVC, H.264, VP8, VC-1) is supported. Also H.264 encoding (1x1080p@30fps or
2x 720p@30fps) is supported.
The board is completed with up to 4GB LPDDR4-3200 32-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 an optional microSD Card slot.
The board can support 24 bit Single Channel LVDS interface.
The processor offers an RMII interface which, through a dedicated Micrel KSZ8091 Ethernet Transceiver, allows the implementation of a FastEthernet interface.
The networking capabilities of this module can be extended through an M.2 Socket 1 Key E slot with UART + SDIO interface, which allows plugging accessory
WiFi+BT M.2 modules.
An additional miniPCI-e slot allows expanding the connectivity possibilities of this board. Since this slot is connected to an on-board microSIM slot, it is possible to
equip the board with external modem modules.
The SBC-D23 board offers two USB 2.0 standard Type-A connectors; another USB interface can be available, as a factory alternative, on an internal header or on
the LVDS connector. The USB OTG interface is available both on a micro-B connector (client mode) an on an additional Type-A connector. Finally, an additional USB
header is available, managed by the on-board microcontroller.
The audio functionalities of this board are managed by the Audio Codec embedded in the RK-809 PMIC, which makes available a stereo output on an internal 3-pin
connector. Managed as factory alternatives, there can be TRRS combo jack for Headphone and Mic-in or a class-D amplified Stereo ouput on micro-fit connector.
Many serial ports are available: up to 2x UART/RS-232 (factory alternatives), 1x CAN port, 2x 2-Wire UARTs and 2x 4-Wire UARTs.
SD23 board incorporates HDMI Technology.
Other interfaces available will be thoroughly described in the following chapters.
