Most industrial gateway projects fail on connectivity, not compute. The RK3568 wins because it removes the daughterboards that usually bridge a machine network to a plant network.
Two independent Gigabit MACs
True network segmentation between the OT machine network and the IT plant network needs two independent interfaces. The RK3568 provides two Gigabit MACs on the base board - no PCIe Ethernet card, no USB adapter.
Fieldbus without breakout boards
Dual CAN-FD and four serial ports cover Modbus RTU/TCP, RS485 and OPC UA side by side. For a gateway that has to speak 1995-era Modbus and 2024-era MQTT, that mix is the whole job.
A supply promise you can put in a contract
Rockchip has committed RK3568 supply into the next decade. We mirror that with PCN discipline and buffer stock, so the gateway you certify in 2026 is still buildable in 2033.
