An ESP32 sensor node, designed by AI

A WiFi sensor node is the classic first connected-hardware project: a microcontroller, a digital sensor, power, and a way to program it. With Ohmni you describe it in a sentence and get back a board you can send to a fab — no schematic capture, no footprint hunting, no routing.

What ends up on the board

USB-C power input with a regulated 3.3 V rail
ESP32 module for WiFi and application code
SHT31 temperature and humidity sensor on I2C with pull-ups
Status LED on a GPIO
6-pin programming header

How Ohmni designs it

The circuit is generated from your description: parts chosen, nets wired, values calculated.
The power rails are simulated and the layout is checked against manufacturing rules. Anything that fails is fixed and rechecked before you see it.
You download gerbers, a BOM, and a 3D preview — ready for JLCPCB, PCBWay, or your usual fab.

The prompt below goes straight into the studio. Edit it there, or use it as-is.

USB-C powered ESP32 WiFi node with an SHT31 temperature/humidity sensor on I2C, a status LED on a GPIO, and a 6-pin programming header. 3.3V rail for the MCU and sensor. Keep it simple: no mains, no relay.
