Velxio: I built an open-source embedded systems simulator with Arduino, ESP32, Raspberry Pi ,AI, SPICE, and retro CPUs
I've been building an open-source embedded systems simulator called Velxio.
It supports:
- Arduino, ESP32, Raspberry Pi Pico and Raspberry Pi emulation
- Multi-board systems communicating over UART, I2C and SPI
- SPICE-based analog circuit simulation with ngspice
- Retro CPUs including Z80, Intel 8080, 4004 and 8086
- MicroSD and ePaper emulation
- An AI agent that can generate circuits and firmware from natural language
Everything runs directly in the browser. No installation, no account required.
You can try it at http://velxio.dev
