The first cut for the QVGA Graphic Control Module Artwork has been completed. It is a four-layer board with power and ground planes. I still have inspection and test fitting of parts before releasing to the shop.
The module is currently 5 x 3.5 inch. There is so much new ground to cover with this new technology, I thought it best to do the control portion first with the existing VGA screen. After proving the controller works ok then merge a custom QVGA screen board as a stacked sandwich item attached to the rear side of the control module.
This benchmark QVGA Controller design has a large capacity SRAM chip and external parallel FLASH chip which we may not need for our application. That could reduced the control board down to about 3.5 x 3.5 inch.
