## What it is
Eclipse MRAA is a C/C++ library with bindings for Python, Node.js, and Java for controlling low-speed I/O (GPIO, I2C, SPI, UART) on GNU/Linux boards. It performs runtime board detection so the same code runs portably across many supported IoT and edge platforms.

## Use cases
- control gpio pins on a raspberry pi from python
- read i2c sensors on an intel edison
- write portable code that works across multiple single-board computers
- drive spi devices from node.js on linux
- blink an led on a beaglebone black
- interface actuators with high-level languages on embedded linux
- prototype iot hardware without vendor-specific sdk lock-in

## When to choose
- you need low-level GPIO/I2C/SPI/UART access on a supported Linux board
- you want portable code across many SBCs via runtime board detection
- you prefer Python, JavaScript, or Java bindings over raw C for hardware I/O

## When to avoid
- your board is not in the supported platform list
- you need high-speed or real-time-critical I/O beyond low-speed buses
- you target microcontrollers or non-Linux embedded platforms

## Facets
- artifact type: library
- maturity: active
- function: embedded, iot, sdk, developer-tools
- domain: iot, embedded-systems, hardware, developer-tools
- platform: c, cpp, python, jvm, embedded
- tags: gpio, i2c, spi, uart, single-board-computers, raspberry-pi, sensor-interface, board-detection, hardware-abstraction, linux, nodejs
