2.4. Embedded Master VGA Expansion
This expansion board is a very simple way to use a standard VGA monitor with
Embedded Master TFT Development System. Users will need to remove the TFT
Expansion included with the development system and replace it with the VGA
expansion. This board can not be used with older non-TFT systems (systems with
smaller modules).
A simple resistor network is used to simulate a DAC. This reduces the color quality on
output images. For better quality, designers should use a DAC circuit instead of simple
resistor network, such as ADV7125 from Analog Devices.
2.5. Embedded Master Module Break-out board
The prototyping breakout board brings all Embedded
Master Module signals out to a 0.1" header. This makes
prototyping easier. The board can plug directly into a
bread-board. The board also includes the pads for
optional USB and Ethernet connectors. Not only that,
there are pads for optional 3.3V voltage regulator so this
board can be powered right from the USB cable. This is a
raw circuit board only and does NOT include any
components or headers, not even the Embedded Master
module.
The EM module's placement pads are located on the bottom side of the circuit board.
Please use the Development System for getting started.
This breakout board requires minimum skills in hand-
soldering.
