Flux

The STM32 might be the most underrated microcontroller out there. 👀

72 MHz, 32-bit ARM core. The Arduino UNO runs 16 MHz on an 8-bit core. That gap is why STM32s end up inside real commercial products.

But you'll never find one of those products with a dev board glued inside. They all run on a custom PCB.

Designing your own STM32 board is easier than you think. Describe what you want and Flux maps out the schematic with you.

Hardware used to take a team and months. That is changing.

The cheapest superpower in DIY electronics ⚡

That little chip hiding inside your power bank, your phone case battery, your portable speaker is wildly accessible, and a perfect first build for anyone curious about designing their own PCBs. 🔋

The whole board was designed end-to-end with AI in Flux.

Your microcontroller decides what your project can actually do.

ESP32 for IoT. Daisy Seed for audio. Something else entirely for motors and sensors.

Pick the chip first. Design the board around it.
