ESP32-S3 Industrial PLC Controller schematic architecture for a 24 V industrial PLC with W5500 Ethernet, isolated RS485, 8 opto-isolated digital inputs, and 8 protected high-side outputs.

Motherboard for a camera gimbal system using off-the-shelf modules where practical, including Wiznet Pico W5500, UART-to-RS232, power supply modules, and BaseCam SimpleBGC 32-bit Extended. Design preference is mostly through-hole modules/connectors with surface-mount support components as needed.

Industrial-grade RP2350B controller with W5500 Ethernet, 24V input power, isolated industrial I/O, RS485, USB hub, relay outputs, and robust connector protection for -40°C to +85°C consumer/industrial use.

UK Smart Wall Switch Back Board: 802.3af PoE-powered 65x65mm relay and energy-monitoring back board with RJ45, isolated 5V/3.3V rails, W5500 Ethernet, BL0942 metering, touch ICs, and 12-pin pogo interface.

10/100 Base-T/TX PHY Ethernet controller that supports PoE with SPI Interface. Based on W5500. Can be used as PoE injector. #project #referenceDesign #template #w5500 #PoE #EtherNet #RJ5
