The Avnet Azure Sphere MT3620 Modules support Microsoft’s Azure Sphere end-to-end solution for highly-secured, WiFi connected Microcontroller (MCU) devices. The production-ready, certified modules come in two versions; an on-board chip antenna module for cost-optimized systems, and an external U.FL antenna module supporting two external antennas for applications requiring higher performance, external antennas. Both modules are pin and footprint compatible, allowing for easy design migration and end-product enhancements.
By integrating all the necessary support and RF front end circuitry onto the small 33 mm x 22 mm module, Avnet has reduced the design time for implementing Sphere-based solutions. More importantly, developers can leverage the modules wireless certifications (pending) for their end-product, saving considerable certification costs and testing time.
The Azure Sphere MT3620 modules supports dual-band 802.11 a/b/g/n WiFi connectivity, a 500 MHz Arm® Cortex™-A7 core for user applications, and two general purpose 200MHz Arm Cortex-M4F I/O subsystem cores designed to support real-time requirements. The on-chip peripherals (GPIO, UART, I2C, SPI, PWM and ADC) can be mapped to dedicated I/O pins on the module for connection to external sensors, I/O connectors, or other user application circuits.
Avnet provides the Azure Sphere MT3620 Starter Kit to jump start Sphere development efforts. The kit includes the chip antenna version of the Azure Sphere MT3620 module and is an ideal starting point for developers wanting to learn the Sphere development environment and quickly deploy proof-of-concept examples for testing and validation.
