Connectivity support

Wireless network connectivity: The first commercially available Azure Sphere chip, the MediaTek MT3620, offers built-in dual-band wireless network connectivity for 2.4 GHz and 5 GHz bands. Extend connectivity to wired Ethernet with an external Microchip ENC28J60 controller.

Ethernet connectivity: Connect your Azure Sphere device to a public 10 Mbps Ethernet network through standard TCP or UDP networking to communicate with Azure IoT or your own cloud services.

Bluetooth LE connectivity: Some scenarios may require connecting Azure Sphere to wireless networks via an additional Bluetooth Low Energy (BLE) chip. Explore BLE options through our rapidly growing partner ecosystem.

Cellular connectivity: Stay secure with Azure Sphere’s software update infrastructure, certificate-based authentication and Azure integration while connecting over a cellular network. Explore options for cellular connectivity through our rapidly growing partner ecosystem.

Our hardware ecosystem

A global network of Microsoft partners delivers revolutionary new IoT hardware – from microcontroller units (MCUs) and crossovers to modules, development kits and guardian devices – to bring Azure Sphere to a broad range of customers and applications.

Silicon chips

Microsoft works with silicon partners who create Azure Sphere-certified chips. These chips are the heart of every Azure Sphere-based device. They contain Microsoft security technology that enables end-to-end, secured connectivity and a hardware root of trust.

MediaTek 3620

This cross-over class of MCUs includes built-in Microsoft security technology and wireless network connectivity, and combines the versatility and power of an Arm Cortex-A7 processor with the low overhead and real-time guarantees of a Cortex-M class processor.

Development Kits

Get up and running quickly and easily test different hardware designs. Azure Sphere development kits feature on-board LEDs and buttons, easy-to-use connectors, and integrated programming and debugging circuitry compatible with the Azure Sphere SDK.

The mobile development kit is the development version of the q200 Guardian with additional connectors for fast prototyping of solutions, WiFi and GNSS included alongside mobile.

Modules for new IoT devices

Build new, connected devices with Azure Sphere modules. One of the challenges of device design is ensuring that WiFi performs well and complies with applicable regulations. These modules remove this obstacle and reduce time to market by providing a tested and production-ready WiFi radio subsystem that’s built around an Azure Sphere-certified chip. Modules provide a range of integrated functionalities and regulatory certifications for target use cases.

Avnet AES-MS-MT3620

This production-ready, dual-band WiFi module is available in two versions: with an integrated antenna and with an external U.FL antenna connector. Both versions are pin- and footprint-compatible. The stamp-hole (castellated) pin design simplifies quality assurance.

AI-Link WF-M620-RSC1

This single-band WiFi module is designed for cost-sensitive applications. It simplifies quality assurance with stamp-hole (castellated) pin design.

USI WiFi module with Bluetooth option

With support for WiFi, Bluetooth Low Energy and Bluetooth 5 Mesh, this module can also work as an NFC tag for non-contact Bluetooth pairing and device provisioning. Available for prototyping.

qiio Concentrator XN

The product is designed for greenfield applications and supports mobile (2G, 3G, 4G), dual-band WiFi, ethernet (WAN) to connect to Microsoft Azure. For geo-positioning, it is equipped with GNSS and qMAPS. This product is pin-compatible to its 5G IoT companion, the Concentrator XNL.

qiio Concentrator XNL

The 5G IoT companion of the Concentrator XN supports mobile(5G IoT (LTE-M, NB2)), dual-band WiFi, ethernet (WAN) to connect to Azure. For geo-positioning, it is equipped with GNSS and qMAPS. This product is pin-compatible to its LTE IoT companion, the Concentrator XN.

Guardian modules for retrofitting existing equipment

Guardian modules provide a quick path to securely connect existing equipment that either doesn’t support connectivity or doesn’t support it securely. A guardian module serves as an intermediary by physically attaching to the equipment via an existing peripheral and to the Internet via WiFi or Ethernet. The critical equipment itself is never exposed to the Internet. Guardian modules often come as complete hardware solutions.

Avnet Guardian 100

The Avnet Guardian 100 attaches to and secures existing equipment via Ethernet or USB, and securely transfers data to and from the cloud over dual-band WiFi.

qiio q200 Guardian

This worldwide mobile device for brownfield IoT applications works from the edge to the cloud upon delivery. It comes ready with embedded software and fully integrated with Azure. Must be prototyped first with qiio development kit.
