Set up your board and install the Azure Sphere SDK

Before you can develop or deploy applications for Azure Sphere, you must first set up your board and install the software.


  • An Azure Sphere Development Kit
  • A PC running Windows 10 Anniversary Update or later
  • An unused USB port on the PC
  • Visual Studio 2017 Enterprise, Professional, or Community, version 15.7 or later. To install Visual Studio, select the edition to install, and then run the installer. You can install any workloads, or none.

Connect the board

The development board connects to a PC through USB. When plugged in, the board exposes three COM ports.

The first time you plug in the board, the drivers should be automatically downloaded and installed. Installation can be slow; if the drivers are not installed automatically, right-click on the device name in Device Manager and select Update driver. Alternatively, you can download the drivers from Future Technology Devices International (FTDI). Choose the driver that matches your Windows installation (32- or 64-bit).

To verify installation, open Device Manager and look for three COM ports. The numbers on your COM ports may be different from those in the figure.
