## What it is
The open-source Device OS firmware for Particle IoT devices, providing the operating system, hardware abstraction layer, cloud communication, and Arduino-compatible application framework running on Particle hardware like Photon, Argon, Boron, and Electron. It is licensed under LGPLv3 and built with the GCC ARM toolchain.

## Use cases
- build firmware for Particle IoT devices
- flash custom application code to a Photon or Boron
- connect embedded hardware to the Particle cloud
- deploy over-the-air firmware updates to device fleets
- port Particle Device OS to new custom hardware
- use Arduino libraries on Particle devices

## When to choose
- you are developing products on Particle hardware (Photon, Argon, Boron, Electron, E-Series, Tracker)
- you need managed cloud connectivity and OTA updates for connected devices
- you want an Arduino-compatible embedded framework with commercial-friendly LGPL licensing
- you need to customize or extend the system firmware or port it to a new HAL

## When to avoid
- you use non-Particle microcontrollers and want a generic embedded framework
- you need a bare-metal RTOS without cloud services
- your project requires a permissive license and cannot accept LGPLv3 terms for system firmware modifications

## Facets
- artifact type: framework
- maturity: active
- function: embedded, sdk, middleware, networking, security, deployment
- domain: iot, embedded-systems, hardware, cloud-computing
- platform: embedded, iot, cpp, c, cross-platform
- tags: particle, firmware, device-os, ota-updates, arduino-compatible, cortex-m, hal, photon, argon, boron, cellular, cloud-connectivity
