500-page datasheets.
Select your MCU, drop in peripherals — Pin2Code maps the pins, detects hardware conflicts, and generates initialization code in seconds.
Every config handled.
Zero hardware casualties.
From pin assignment to conflict detection to production-ready init code — everything you used to do manually, automated.
Visual Pin Mapper
Click peripherals onto an interactive MCU chip diagram. See occupied pins update in real time.
Conflict Detector
Hardware timer conflicts, shared SPI buses, voltage mismatches — flagged instantly with fix suggestions.
Code Generator
Full Arduino C++, STM32 HAL, MicroPython, or ESP-IDF init code — not just pin defines.
Bill of Materials
Automatic BOM with component prices, resistor values, and notes for every peripheral you add.
Save Configs
Save and reload your configurations. Share public configs with your team or classmates.
AI Assistant
Describe your project in plain English — AI configures pins and generates complete code.
Four steps to working hardware.
Choose from 20+ supported microcontrollers including ESP32, STM32, Arduino, and Raspberry Pi.
Click DHT22, OLED, GPS, Servo, LoRa and more from the library — pins auto-assign.
Pin2Code flags every hardware conflict with a clear description and suggested fix.
One click to copy complete initialization code. Arduino, MicroPython, HAL — your choice.
Never fry a lab board again.
