The Avnet Azure Sphere MT3620 Starter Kit supports rapid prototyping of highly secure, end-to-end IoT implementations using Microsoft’s Azure Sphere. The small form-factor carrier board includes a production-ready MT3620 Sphere module with WiFi connectivity, along with multiple expansion interfaces for easy integration of off-the-shelf sensors, displays, motors, relays, and more. The downloadable getting started tutorial guides developers through the development steps from board setup to application coding.
The production-ready Sphere MT3620 module is based on the MT3620 SoC, which includes built-in Microsoft security, WiFi connectivity and the combined versatility and power of an Arm® Cortex™-A7 processor with the low overhead and real-time guarantees of two Arm Cortex-M4F microcontrollers. 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. Up to 27 configurable GPIOs and three configurable serial ports (UART, I2C, or SPI) are provided as I/Os on the module.
The carrier board connects the Sphere module I/Os to two MikroE Click sockets, an I2C Grove connector, a connector supporting the addition of a 128 x 64 OLED graphical display, a 3D accelerometer, 3D Gyro, temperature sensor, and an ambient light sensor. Debugging is accomplished through a USB-to-UART interface, which also provides the necessary 5V power for the board.
User applications for the embedded Sphere controller are developed in C using Microsoft’s Visual Studio IDE and the 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, and the production ready Sphere module delivers a powerful starting point for IoT developers interested in learning, prototyping, and deploying Azure Sphere based solutions.
