A GPS tracker with onboard logging, designed by AI

A position logger is two buses working together: a GPS receiver streaming fixes over UART and a flash chip recording them over SPI. Ohmni wires both to the ESP32, budgets the rail for the GPS receiver’s acquisition current, and hands you a board ready to track.

What ends up on the board

  • USB-C power input with a protected, regulated 3.3 V rail
  • ESP32 module for WiFi and the application
  • GPS receiver on UART
  • W25Q128 SPI flash — 16 MB of track storage
  • Status LED and programming header

How Ohmni designs it

  1. The circuit is generated from your description: buses assigned, pins allocated, rail sized for GPS acquisition current.
  2. The rail is 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.
