INSTALL THE OS

An operating system needs to be installed onto the Micro SD card before inserting it into the RasPad button-board.

Note

Skip this chapter if the Raspberry Pi already has an operating system installed.

Raspberry Pi Imager is a quick and easy way to install the Raspberry Pi operating system to a Micro SD card from a computer or laptop.

Browse to the Raspberry Pi Imager site and download the version that matches the computer or laptop’s operating system (www.raspberrypi.org/software). When the download is complete, launch the installer program and follow the prompts to install the Raspberry Pi Imager.
