Non-Windows XP Users download version 1.4.0 driver.
Windows XP Users download version 1.3.1 driver.
- Linux users to ensure that you have the correct permissions to connect as a normal user you'll need to copy the file 45-espruino.rules to /etc/udev/rules.d, reload rules with udevadm control --reload-rules, and ensure your user is in the plugdev group (you can check by typing groups). You can add it by typing sudo adduser $USER plugdev and then logging out and back in. Arch Linux users need to add their user to uucp and lock groups instead.
- Mac OS X and Chromebook Users: The board will just plug in and work, without a driver!
Once you finish installing the driver, your computer can recognize the Espruino device.
