Creating Pi Image:
- Get an SD Card Formatter and Imager (Windows can be used to format, and BalenaEtcher is a recommended Imager)
- SD Card must be at LEAST 4GB size
- Format SD Card with FAT32
- Image Pi with correct image from pi-star site: Click Here
- Load SD card into RaspPi and allow to boot
Configure Pi-Star:
- Connect to RaspPi via Wifi
- SSID: pi-star
- Password: raspberry
- Navigate in browser to http://pi-star.local/
- Log into pi-star (default login is same as wifi login)
- Configure and
