The RK3588_ETH is a single-board computer purpose-built as a Linux,
Xenomai and IgH real-time EtherCAT solution based on the Rockchip
RK3588S. Despite its compact size it functions as a full
single-board PC, combining 8 GB of RAM, 32 GB of eMMC flash, 8K
video decoding and an integrated 6 TOPS NPU for AI workloads. It is
aimed at EtherCAT masters, motion control and industrial automation
applications that need deterministic real-time networking.
The RK3588S SoC is an octa-core processor with four Arm Cortex-A76
cores at 2.4 GHz and four Cortex-A55 cores at 1.8 GHz, paired with
an Arm Mali-G610 MP4 GPU supporting OpenGL ES3.2, OpenCL 2.2 and
Vulkan 1.1. The VPU handles 8KP60 H.265, VP9 and AVS2 decoding,
8KP30 H.264 decoding, 4KP60 AV1 decoding and 8KP30 H.265/H.264
encoding, while the 6 TOPS NPU accelerates on-device AI inference.
For networking the board provides two 2.5GbE RJ45 ports based on
Realtek RTL8125BG PCIe cards with a maximum throughput of 2.35
Gbps, plus one Gigabit RJ45 port based on the Realtek RTL8211F with
a tested speed of 941 Mbps, making it well suited to EtherCAT and
high-bandwidth industrial networks. An HDMI 2.1 port supports up to
8KP60 or 4KP120 output, and a 12-pin FPC connector breaks out 1
SPI, 3 UARTs, 1 I2C and 8 GPIOs for expansion. The board measures
90 x 62 mm and operates from 0 to 70 C.
