Introduction
1.2. What is Embedded Master Module
Embedded Master Module is a very small RoHS hardware module (1.55”x1.55” for non-
TFT version and 1.55”x1.8” for TFT version) that hosts the Microsoft .NET Micro
framework. Developers can now use .NET Micro Framework 3.0 and write managed code
(C#) without having to deal with much complexity of hardware and software. Embedded
Master Module is fully licensed to use .NET Micro Framework.
In addition to .NET Micro Framework standard features, Embedded Master Module has
many exclusive additional features that are not supported in other .NET Micro Framework
platforms, such as USB Hosting, Analog inputs, Analog outputs, PWM, CAN and more.

1.2.1 Embedded Master Non-TFT vs TFT
The TFT version of Embedded Master modules uses identical processor but with an
LCD controller (LPC2478). The new module is only 0.25 inches larger on one side to
add an LCD connector. It also adds more analog and PWM pins. It has a total of 70
pads (60 pads on Non-TFT). The new TFT module is 1.8”x1.55”, whereas, the Non-TFT
is 1.55”x1.55”. Note that all LCD required pins are on a separate 40-pin 0.5mm FPC
connector. Also, these modules still support the low-cost low-resolution displays that are
refreshed from a dedicated SPI bus, same as the original Non-TFT modules.
The Non-TFT Embedded Master Module only supports low-cost low-resolution displays
which uses a SPI bus to transfer the video buffer to.
Make sure your design is made to accept the TFT version of the module. The TFT pads
are compatible with Non-TFT version.
