$4 buys you a dual-core 32-bit ARM computer. 🔍

The Raspberry Pi Pico packs an RP2040, Quad-SPI flash, a 3.3V buck-boost regulator, and a full row of GPIOs.

Want that chip on your own board instead of the dev kit? Describe the project to Flux and it builds the schematic, layout, and traces.

Progress.

You've seen this board a thousand times. But do you actually know what's on it? 🔬

We rebuilt the whole thing in Flux, and added sensors and an LED matrix.

Designing your own board is easier than you think.

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.

Designing your own ESP32 board is way simpler than it looks. ⚡

Four parts get you a working barebones design 👇

🔌 USB-C port
⚙️ Voltage regulator
🧠 ESP32-S3 module
🔘 Boot + reset buttons

That's it. From there, add whatever the project needs, a DAC for audio, a mic, sensors, displays. The board is yours.

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.

Today, we built a bird sound generator PCB with AI.

I listed the parts, told Flux a few constraints, and it generated the entire board.

From prompt to finished PCB!

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.

Hardware design doesn’t happen in a straight line.

You start with an idea, but things take a turn in the middle. Parts change. Requirements sharpen. You get the drift. 🏎️💨

That’s where most hardware projects slow down, or worse, stop entirely.

Today, we released an update to the Flux agent. Tell it mid-build that you want a rechargeable battery, swap in a different MCU, or move a connector, and it adapts without restarting. ✨

Your hand’s on the wheel.

PCB MIDI controller schematic designed with AI in under 3 minutes. ⚡️

Three sliders, eight buttons, three rotary encoders, a Raspberry Pi Pico. All wired up by Flux from a single prompt.

The trick is writing the right one.

Comment “schematic” for the full prompt guide.
