RK3576 as an Industrial Gateway: CAN-FD and Serial Ports in Practice
Industrial gateways are about interfaces and reliability, not raw compute — exactly where RK3576 focuses at the silicon level.
Gateway capability list
- Interfaces: 2× CAN-FD, 4× RS485/232, dual gigabit — PLCs and meters connect directly;
- Protocols: Modbus RTU/TCP, OPC UA and MQTT bridges all have mature stacks;
- Wide temp: -20~70°C board design, no cabinet cooling needed;
- Store-and-forward: local SQLite buffering replays data after outages.
Typical topology
Shop floor: one RK3576 gateway chains ten PLCs and pushes MQTT upstream. A single unit sustains 200+ tags at 1-second polling — an ideal tier to replace aging IPCs.
