GoKawiilVelxio: Arduino & Embedded Board Emulator
Live at velxio.dev
A fully local, open-source multi-board emulator. Write Arduino C++ or Python, compile it, and simulate it with real CPU emulation and 48+ interactive electronic components — all running in your browser.
19 boards · 5 CPU architectures: AVR8 (ATmega / ATtiny), ARM Cortex-M0+ (RP2040), RISC-V RV32IMC/EC (ESP32-C3 / CH32V003), Xtensa LX6/LX7 (ESP32 / ESP32-S3 via QEMU), and ARM Cortex-A53 (Raspberry Pi 3 Linux via QEMU).
Support the Project
Velxio is free and open-source. Building and maintaining a full multi-board emulator takes a lot of time — if it saves you time or you enjoy the project, sponsoring me directly helps keep development going.
