Graphics terminal board

Schematics and a PC board to drive a SainSmart 20-011-918 TFT. The display is a 320x240 pixel display, 16 bits deep per pixel. The board is driven by a PIC32MX250F128B or a PIC32MX150F128B. To conserve PIC pins the TFT is driven through two Microchip MCP23S17 I/O expanders. The board requires 5 volt power and uses a LM78L33ACZ to convert that to the 3.3 volt power required by the PIC and LCD.

The project includes gschem schematics, pcb printed circuit layouts, as well as Gerbers. The most recent set of Gerbers sent for production are preserved in a zip file named with the commit of the appropriate layout. Earlier zips (and Gerbers) are deleted, so earlier commits must be viewed to see earlier zips.

Versions sent to production are tagged with tags beginning with Rev and the commit message identifies the manufacturer.
