r/circuitpython

Been building IoT projects every day for my #100DaysOfIoT challenge and kept running into the same problem — monitoring sensor data from ESP32/Pico 2W in a browser was always a mess.

So I built micropidash. real-time web dashboard in under 20 lines of MicroPython. No cloud, no framework.

Just shipped v2.0.0 with live sensor graphs — tested with DHT11 on Pico 2W, temp + humidity updating in the browser over WiFi.

pip install micropidash

Would love feedback if you try it!

I created an MCP server that lets Codex access a Raspberry Pi Pico running CircuitPython.

With it, Codex can inspect the board, read and edit files, deploy code, run programs, reset the Pico, and watch serial output. Since Codex already understands CircuitPython, it can help write real board-ready code, and it can even find the correct Adafruit libraries online and install them for you.

Gotta love it.
