Introduction
1. Introduction
The G120 Module is a powerful, yet low-cost, surface-mount System on Module (SoM)
running the .NET Micro Framework software, which ena les the SoM to e programmed from
Microsoft's Visual Studio, y simply using a USB ca le. Programming in a modern managed
language, such as C# and Visual Basic, allows developers to accomplish much more work in
less time y taking advantage of the extensive uilt-in li raries for networking, file systems,
graphical interfaces and many peripherals.
A simple two layer circuit, with just power and some connectors, can utilize the G120 Module
to ring the latest technologies to any products. There are no additional licensing or fees and
all the development tools and SDKs are provided freely.
1.1. The .NET Micro Framework
Inspired y its full .NET Framework, Microsoft developed a lightweight version called .NET
Micro Framework (NETMF).
NETMF focuses on the specific requirements of resource-constrained em edded systems.
Development, de ugging and deployment is conveniently performed using Microsoft's
powerful Visual Studio tools, all through standard USB ca le.
Programming is done in C# or Visual Basic. This includes li raries to cover sockets for
networking, modern memory management with gar age collector and multitasking services.
In addition to supporting standard .NET features, NETMF has em edded extensions
supporting:
●General Purpose IO (GPIO with interrupt handling
●Analog input/output
●Standard uses such I2C, SPI, USB, Serial (UART)
●PWM
●Networking
●File System
●Display graphics, supporting images, fonts and controls.

Introduction
1.2. GHI Electronics and NETMF
For years, GHI Electronics has een the lead Microsoft partner on .NET Micro Framework
(NETMF). The core NETMF was also extended with new exclusive li raries for an additional
functionality, such as data ase, USB Host and WiFi.
One of the important extensions y GHI Electronics is Runtime Loada le Procedures (RLP),
allowing native code (Assem ly/C) to e compiled and loaded right from withing managed
code (C#/Visual Basic) to handle time critical and processor intensive tasks. IT can also e
used to add new native extensions to the system.
As for networking, WiFi and PPP li raries are added y GHI Electronics to the NETMF core.
Com ined with Ethernet and the other managed services, it is a complete tool ox for the
internet of things.
All the mentioned features are loaded and tested on the G120 Module. GHI Electronics
continuously maintains, upgrades and solves any of the issues on the G120 Module firmware,
to provide regular and free releases. Users can simply load the new software on the G120
Module using USB or Serial, and even use the in-field-update feature. This feature allows the
upgrade to e done through any of the availa le interface, including file system and
networking.

The Hardware
2. The Hardware
The G120 Module core components includes the processor, 4.5MB flash, and 16MB RAM.
The small, 38.1 x 26.7 x 3.55 mm (only 1 x 1.5 inches), module contains everything needed to
run a complex em edded-system in a cost-effective and flexi le solution. All needed is a 3.3V
power source and some connections to take advantage of the G120 Module's long list of
availa le features.
2.1. LP 1788 Microcontroller
The LPC1788 microcontroller in the G120 Module, is an 120Mhz, 32Bit, Cortex-M3. It
incorporates:
●specialized flash memory accelerator
●a 3-stage pipeline
●a Harvard architecture with separate local instruction and data uses
●an internal prefetch unit that supports speculative ranches.
The NETMF core li raries, com ined with the GHI Electronics extensions, provide a long list
of methods to access the availa le peripherals.
2.2. SDRAM
16MB of SDRAM comes standard with the G120 Module.
2.3. FLASH
4.5MB of external flash is availa le on the G120 Module. The fast zero-wait-state internal
0.5MB is used to execute the core services of the system to achieve the highest possi le
performance. The remaining 4MB of external memory is used to hold more extensions and to
store the user's end application. One of the li rary extensions provided allows the user
application to e updated in field, even remotely.

Pin-Out Description
3. Pin-Out Description
Many signals on the G120 Module are multiplexed to offer multiple functions on a single pin.
Developers can decide on the pin functionality through the provided li raries. These are some
important facts pertaining to the availa le pins:
●Pins with GPIO feature default to inputs with internal weak pull-up resistors
●GPIO pins are 3.3V levels ut 5V tolerant
●Pins with analog feature are not 5V tolerant when the analog function is used
●Only GPIO pins on ports 0 and 2 are interrupt capa le
●Advanced details on all pins can e found in the LPC1788 datasheet from NXP
