Describe it in a sentence
Plain English in, a complete design out — firmware, wiring and the parts list, rather than a code snippet that assumes pins that do not exist.
Fourteen checks before you build
Board pin rules, electrical rules, a real compile through arduino-cli, power budgeting and copper matched against the netlist. Errors get caught before the soldering iron, not after.
Simulate in the browser
The circuit runs before it exists. No breadboard, no ordering parts to find out the design was wrong.
Flash over USB
Straight to a connected Arduino or compatible board from the browser, with no toolchain to install first.
AI PCB designer
Automatic component placement and routing, producing Gerber files a fab house accepts.
Eleven supported boards
Arduino Uno R3, Mega 2560, Nano, Leonardo and Nano RP2040 Connect; Raspberry Pi Pico and Pico W; ESP32 DevKit V1, C3 and S3; NodeMCU ESP8266.
