Hardware requirements

  • Cloudio
  • Raspberry Pi 1/2/3/0/0W
  • External Wi-Fi dongle (in case of Raspberry Pi 0/1/2)
  • SD card (8 GB or higher) with GraspIO OS (To be inserted into Raspberry Pi)
  • Power supply (As recommended by Raspberry Pi; more details here)
    (For best use of all the peripherals on Cloudio, we recommend a 5V, 2A power supply)

Additional optional hardware

Raspberry Pi camera or USB camera

(For projects that use camera applications using the Camera block)

Camera connected to Raspberry Pi

To connect the Raspberry Pi camera, please follow the steps explained here

Connecting a USB camera

If you're using a Raspberry Pi 0 or 0W, you'd need to use an OTG cable to connect the USB camera to the Raspberry Pi.


(For projects that use speaker applications using the Speak block)

The speaker is to be connected to Raspberry Pi's audio jack.
