An isolated Modbus-to-LoRa gateway, designed by AI

This is the kind of board people assume AI cannot do: mains power, a galvanically isolated fieldbus, and a long-range radio on one PCB. Ohmni handles the domain discipline for you — mains, isolation barriers, and the SELV side are kept separate and checked, not left to hope.

What ends up on the board

• 85–265 VAC mains input with protection
• Isolated AC/DC module supplying the logic rail
• ESP32 module for the application
• Isolated RS-485 transceiver (ADM2587E) for Modbus
• LoRa radio on SPI for long-range uplink
• Status LED and programming header

How Ohmni designs it

1. The circuit is generated with the mains and low-voltage domains separated by declared isolation barriers — the electrical rule check enforces it.
2. Supply rails are simulated and the layout is verified against manufacturing rules before you see it.
3. You download gerbers, a BOM, and a 3D preview, ready for your fab.
