for $35.00 including shipping. It also has a touch screen and controller , eeprom, and sd socket.
Below is the test code. This should get you started if you want to play with this color display.
I am using 8 bit control for the LCD and hardware SPI for the touch screen controller.
Here are the spec's
3.5" QVGA 262k TFT-LCD module
240*RGB*320 pixels
LCD driver is SSD2119
2.7-3.3V operating voltage
RS1843 touch panel controller onboard directly compatible with ADS7843
Standard 2.54mm PCB headers for prototyping
Support a SD card interface(SPI mode)
Support a ATMEL DataFlash AT45DBxxx series device
Optional 8-bit or 16-bit parallel bus interface and
Optional 3 wire SPI or 4 wire SPI interface with PS3、PS2、PS1、PS1 jump select
4-wire Touch Panel support
I have to give credit to Darrel Taylor, mister_e, skimask and anyone else I may have used their code over the years.
