• skaarOS image file   (this can only be obtained from SKAARHOJ Customer Support)

  1. make sure you have the 'skaarOS' image file ready on your Desktop (you get this file from SKAARHOJ Customer Support)
  2. open BalenaEtcher app (remember, this must be version 1.18 or later)
  3. click 'Flash from file' > select the 'skaaros_xxxx' image file from the Desktop (pic 1 and 2)
  4. click 'Select target'
  5. connect Blue Pill device to computer via USB > hold paperclip pressed in the configuration hole on the device > connect power (PSU or PoE) to device (pic 3)
  6. when you see 'Compute Module' in BalenaEtcher, remove paperclip
  7. select 'Compute Module' > click 'Select' (pic 4)
  8. click 'Flash!' > enter computer password > wait approx 5 min (pic 5)
  9. after flash procedure is done, quit BalenaEtcher
  10. disconnect USB and power from Blue Pill device > connect power again to reboot (will take approx 0,5-1 min)

The Blue Pill device should start up, and display the DHCP IP address it can be found at.
- For initial setup we recommend a network with DHCP server -
