Download and Flash

Two steps:

Download the firmware

The firmware is a very big file (many Gb) that is downloaded from the cloud and then written on the SDCard that will then be inserted in the Raspberry Pi. As this firmware runs on the Pi, it is the same if you use Windows or Macintosh.

If you are using a Thingbox: Download the image from

If you are using a TimeSquAir: Download the image from . As TimeSquair is shipped with an already in place SDCard, this only applies to rebuild a card.

Write the SDCard

Etcher is the application to write the firmware on the SD card

Etcher ( turns the whole process of flashing an OS image file into three simple steps: Select Image, Select Drive, and Flash Image. More importantly, the same program, with the same interface, is available on all three types of computer – Windows, Mac, and Linux – which makes it easy for everybody to understand.

More in :

  • Download and install Etcher from the website.
  • Launch the application file and follow the Etcher setup wizard.
  • Click “Select Image” in Etcher. Use the file manager window and locate the zip file you dowloaded (there is no need to unzip it). Click Open. The image will appear under Select Image, and Connect a drive will highlight red.

Warning : the SD card will be totally over-written, so this SD card should be used only for the Raspberry Pi.

  • Insert your SD card in the computer. Etcher will select it automatically. Etcher won’t write to your hard drives by default, but check that the SD card is listed correctly. Now click Flash! to write the image file to the SD card.


Etcher will format the SD card, before writing and verifying the image; this is shown by a progress bar. When done, remove the SD card, insert it into your Raspberry Pi, and power it up.

The first boot is longer because it expands the SDCard to use the free part of the SDCard. Then reboot again.

If you don’t want to use WiFi, plug the local network wire BEFORE powering the device.
