Industrial 12–24 V ESP32-S3 gateway with dual isolated Modbus RS-485, native USB-C, and a W5500 module header.

Industrial ESP32-S3 master gateway with Ethernet (W5500), LoRa 433 MHz, microSD storage, RTC, USB-UART console/debug interface (CP2102N), and isolated RS485 ports using ADM2587 transceivers. The design includes ESP32-S3-WROOM-1-N16R2 as the main controller, W5500 Ethernet, LoRa antenna interface, microSD connector, RTC circuitry, CP2102N USB-to-UART programming/debug console, SC16IS752 UART expanders, isolated RS485 channels, power regulation, ESD/surge protection, connectors, and mounting holes. Cellular/BG95/SIM functionality and true RS232 console hardware are not included; J1 is used only as the microSD card connector.

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.
