Show HN: Embedr, an AI copilot for embedded engineers

I have been building embedded projects for years and always felt the tooling lagged behind software dev. Things like quick prototyping, debugging messy hardware specific issues, or figuring out why a peripheral is not responding still take way too long.

So I built Embedr, an AI copilot focused on embedded engineering. It is not a general code assistant. It is tuned around real hardware workflows like:

- Reading your project structure and understanding your board setup - Helping with ESP32, STM32, RP2040 and similar MCU projects - Explaining registers, peripheral configs, linker issues, build errors - Suggesting fixes for hardware faults and integration problems - Letting you pick toolchains or generate build systems - Walking you through bring up steps and driver level debugging

My goal was to get closer to an IDE that works with you while you are wiring, flashing, or debugging boards.

This is still early, and I am actively improving model behavior, prompt flows, and tooling integration. I would love feedback from people who work with microcontrollers daily. What feels useful, what feels wrong, what should it learn next.
