Introduction
1. Introduction
The G30 SoC is a powerful, yet low-cost, surface-mount System on Chip (SoC) running
the .NET Micro Framework software, which enables the SoC to be programmed from
Microsoft's Visual Studio, through a USB cable. Programming in a modern managed
language, such as C# and Visual Basic, allows developers to accomplish much more work in
less time by taking advantage of the extensive built-in libraries for networking, file systems,
graphical interfaces and many peripherals.
A simple two layer circuit, with just power and some connectors, can utilize the G30 SoC to
bring the latest technologies to any products. There are no additional licensing or fees and all
the development tools and SDKs are freely available.

1.3. The .NET Micro Framework
Inspired by its full .NET Framework, Microsoft developed a lightweight version called .NET
Micro
Framework (NETMF).
NETMF focuses on the specific requirements of resource-constrained embedded systems.
Development, debugging and deployment is conveniently performed using Microsoft's
powerful Visual Studio tools, all through standard USB cable.
Programming is done in C# or Visual Basic. This includes libraries to cover sockets for
networking, modern memory management with garbage collector and multitasking services.
In addition to supporting standard .NET features, NETMF has embedded extensions
supporting:
●
●
●
●
●
●
●
General Purpose IO (GPIO with interrupt handling
Analog input/output
Standard buses such I2C, SPI, USB, Serial (UART)
PWM
Networking
File System
Display graphics, supporting images, fonts and controls.
