Welcome to Azure Sphere MT3620 Starter Kit V2

The Azure Sphere MT3620 Starter Kit V2 supports rapid prototyping of highly secure, end-to-end IoT implementations based on Microsoft Azure Sphere. This small form-factor carrier board includes a production-ready MT3620 Sphere module with WiFi connectivity, along with multiple expansion interfaces facilitating easy integration of sensors, displays, motors, relays and more. Key features of this version are its ability to support a wired Ethernet network connection (requires MikroE ETH click adapter to be fitted) as well as more flexibility in how ISUs can be used. Downloadable documentation and tutorials guide developers through all steps, from board setup to application coding.

The version 1 kit has been discontinued.

Technical Specification

The Avnet-designed, production-ready, certified Azure Sphere MT3620 module is based on the MT3620 SoC, which includes built-in Microsoft security, WiFi connectivity plus the versatility and power of an Arm Cortex-A7 processor and two real-time Arm Cortex-M4F microcontroller cores. A suite of on-chip peripherals, real-time clock, Flash and RAM are also available. In addition to the MT3620, the 33 x 22 mm module includes a dual-band WiFi chip antenna and system clock source. Up to 27 configurable GPIOs and three configurable serial ports (UART, I2C or SPI) are accessible on the module pinout.

The carrier board connects the Sphere module I/Os to two MikroE Click sockets, an I2C Grove connector, a connector supporting the addition of an optional 128 x 64 OLED graphical display, a 3D accelerometer, 3D gyro, temperature sensor and ambient light sensor. Debugging is accomplished through a USB-to-UART interface, which also provides 5V power to the board.

User applications for the embedded Sphere controller are developed in C using Microsoft’s Visual Studio IDE and Azure Sphere SDK. Visual Studio provides a powerful yet easy-to-use development environment for compiling and debugging application code. The combination of Visual Studio, the versatile carrier card plus the production-ready Sphere module delivers a powerful starting point for IoT developers interested in learning, prototyping and deploying Azure Sphere-based solutions.
