MT3620 Mini Dev Board is a Cheaper Microsoft Azure Sphere Board

MT3620 Mini Dev Board

Announced nearly one year ago, Microsoft Azure Sphere is an ecosystem comprised of Azure MCUs with Microsoft Pluton Security System, Linux based Azure Sphere OS, and a secure cloud service called Azure Sphere Security Service. The first official Azure development board – MT3620 Development Board for Azure Sphere – was launched last year for $84.95. The kit may not have attracted a large number of developers, so there’s now a cheaper version – MT3620 Mini Dev board – going for $34.90 on Seeed Studio. Note that’s a pre-order and shipping is scheduled for May 13, 2019. MT3620 Mini dev board specifications: CPU Module – AI-Link WF-M620-RSA1 module with Mediatek MT3620AN single core Arm Cortex-A7 processor @ 500 MHz with 4MB SRAM, dual core Arm Cortex-M4F real-time core @ 200 MHz with 64KB RAM, Pluton security sub-system, and WiFi.
