use case

A battery-powered LoRa field node, designed by AI

Off-grid nodes live or die by their power tree. This board runs a real cascade — Li-ion cell, charger with power path, boost to 5 V, then a clean 3.3 V rail — and every stage is sized and simulated against the radio’s transmit bursts, not just its idle draw.

What ends up on the board

Single-cell Li-ion battery with a TP4056 charger and USB-C input
Boost converter to 5 V, then a low-noise 3.3 V rail
ESP32 module for the application
LoRa radio on SPI for kilometres of range
Status LED and programming header

How Ohmni designs it

The power cascade is generated stage by stage, with each rail sized for continuous load and radio transmit peaks separately.
Rails are simulated and the layout is verified against manufacturing rules before you see it.
You download gerbers, a BOM, and a 3D preview, ready for your fab.
