## Velxio：本地 Arduino & Raspberry Pi Pico 开发 Velxio 是一款免费且开源的、基于浏览器的 Arduino 和 Raspberry Pi Pico 项目编辑器和模拟器。它提供了一个完整的本地开发环境——无需账户、云连接或延迟。主要功能包括具有语法高亮显示的 Monaco 代码编辑器、真实的 AVR8/RP2040 CPU 模拟、库管理器和串口监视器。它支持超过 48 种交互式电子元件，并使用 `arduino-cli` 后端将代码编译成标准的 `.hex` 或 `.uf2` 文件。 Velxio 被定位为 Wokwi 的自托管替代方案，利用了相似的开源库，但完全在您的机器上运行（通过浏览器或 Docker）。目前支持 Arduino Uno 和 Raspberry Pi Pico，并计划在未来添加更多开发板。它采用 GNU AGPLv3 许可，并提供商业许可。

## Velxio：浏览器中的Arduino模拟器开发者dmonterocrespo创建了Velxio (velxio.dev)，一个完全本地、开源的Arduino模拟器，直接在您的网页浏览器中运行。该项目旨在探索模拟器内部原理，如CPU指令和内存管理，允许用户编写、编译（使用arduino-cli）和模拟Arduino草图，并具有真实的AVR8 CPU仿真。目前支持Arduino Uno/Nano和Raspberry Pi Pico (RP2040)，Velxio具有交互式电子元件和常用外设，如GPIO、SPI、I2C、UART和ADC。其目标是提供一个易于访问、无需安装的环境，用于实验嵌入式系统。该项目仍在实验阶段，但已经可用，开发者正在积极寻求来自嵌入式开发社区的反馈。代码可在GitHub上找到：[https://github.com/davidmonterocrespo24/velxio](https://github.com/davidmonterocrespo24/velxio)。

Write Arduino code, compile it, and simulate it with real AVR8 CPU emulation and 48+ interactive electronic components — all running locally in your browser. No cloud, no latency, no account required.

Features

Real ATmega328p (AVR8) emulation at 16 MHz via avr8js
Raspberry Pi Pico (RP2040) emulation via rp2040js
48+ wokwi interactive electronic components (LEDs, resistors, buttons, sensors…)
Monaco Code Editor with full C++ / Arduino syntax highlighting
arduino-cli compilation backend — produces real .hex / .uf2 files
Serial Monitor with auto baud-rate detection and send
Library Manager for Arduino libraries
Multi-file workspace (.ino, .h, .cpp)
Wire system with orthogonal routing
ILI9341 TFT display simulation
I2C, SPI, USART, ADC, PWM support
Docker standalone image — deploy anywhere with one command

Supported Boards

Arduino Uno (ATmega328p) — full AVR8 emulation
Raspberry Pi Pico (RP2040) — RP2040 emulation

Get Started

Open the Editor — no installation needed.
Self-host with Docker: docker run -d -p 3080:80 ghcr.io/davidmonterocrespo24/velxio:master

Frequently Asked Questions

Is Velxio free?: Yes. Velxio is free and open-source under the GNU AGPLv3 license. A commercial license is available for proprietary integrations.
Does Velxio work offline?: The simulation engine runs entirely in the browser. Compilation requires the local arduino-cli backend. Self-hosted deployments work fully offline once running.
Is Velxio a Wokwi alternative?: Yes. Velxio is a free, self-hosted alternative to Wokwi. It uses the same avr8js and wokwi-elements open-source libraries but runs on your own machine.
What boards are supported?: Arduino Uno (ATmega328p / AVR8) and Raspberry Pi Pico (RP2040). More boards are planned.
