MT3620 Mini Dev Board is a lite version of Seeed previous Azure Sphere MT3620 Development Kit. For an introduction to Azure sphere, please refer to this link Azure Sphere 

We developed this board to meet the needs of developers who need smaller sizes, are more scalable, and have lower costs. This development board is based on the MT3620 module, which greatly simplifies the difficulty of hardware design. The MT3620 module is developed by our partner AI-Link. Developers can easily reuse this design into their own projects. The development board uses two single-row pin headers for easy plug-in on other motherboards or expansion boards. Unlike the full-featured Azure Sphere MT3620 Development Kit, this development board optimizes the design by reducing some system hardware peripheral resources, and only provides the necessary hardware resources to developers. In terms of hardware specifications, we only support 2.4G Wi-Fi and reduce I2S and some GPIO ports.  

What’s new of the MT3620 Mini Dev Board?

Based on MT3620 module (WF-M620-RSA1)

Reduce the board size from 50mm*80mm*16mm to 34mm*60mm*19mm

Keep the necessary LED indicator and buttons

The board form factor is more easier for add-on usage

The Azure Sphere operating system is pre-installed on the MT3620 and is designed to work with the Azure Sphere Security Service to create a secured IoT platform. Together the Azure Sphere OS and security service deliver: 

• certificate-based device authentication to any web service
  
• software attestation and secure boot
• threat detection via failure reporting
• ongoing security updates
• an integrated, secured end-to-end IoT solution

MT3620 software development is supported using the powerful Microsoft Visual Studio IDE: Install Visual Studio and the Azure Sphere extension, plug the development board into a PC over USB, and start developing IoT applications with unprecedented levels of security.

Key Features

• Azure Sphere: End-to-end security for IoT devices.
  
• Wi-Fi 802.11 b/g/n.
• Tri-core microcontroller with on-chip RAM And flash.
• Microsoft Visual Studio development environment.
• Online authentication and updates for device lifetime.
• Expand UART, I2C, SPI, ADC, GPIO resource on pin header.
