This library provides best-guess platform detection for a range of single-board computers and (potentially) other platforms. It was written primarily for use in Adafruit_Blinka, but may be useful in other contexts.

Platform detection is divided into “chip” and “board” detection, with the latter generally dependent on the former. Platform info is gathered from:

  • Python’s sys.platform
  • Various files on Linux systems:
    • /proc/cpuinfo (for processor info, Raspberry Pi hardware revisions, etc.)
    • /proc/device-tree/compatible (for 96Boards info)
  • Beaglebone EEPROM board IDs
  • Distribution-specific files such as /etc/armbian-release.

Dependencies

This driver depends on:

  • Python 3.5 or higher

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install Adafruit-PlatformDetect

To install system-wide (this may be required in some cases):

sudo pip3 install Adafruit-PlatformDetect

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .env
source .env/bin/activate
pip3 install Adafruit-PlatformDetect

Usage Example

from adafruit_platformdetect import Detector
detector = Detector()
print("Chip id: ", detector.chip.id)
print("Board id: ", detector.board.id)

# Check for specific board models:
print("Pi 3B+? ", detector.board.RASPBERRY_PI_3B_PLUS)
print("BBB? ", detector.board.BEAGLEBONE_BLACK)
print("Orange Pi PC? ", detector.board.ORANGE_PI_PC)
print("generic Linux PC? ", detector.board.GENERIC_LINUX_PC)
