Adafruit TFP401 HDMI/DVI Decoder to 40-Pin TTL Breakout - With Touch
We have two versions, one is video only and one is video+touch. This is the version with touch! Pair it with a screen that has a resistive touch overlay. The USB port then acts as both power and data, with the touch screen appearing like a USB mouse. We've tested it sucessfully on Mac, Windows, and Debian Linux (Raspbian on a Raspberry Pi). Other Linux distributions may or may not work, but if you're running Linux you're probably used to that.
This driver is designed specifically as a small and easy to use display driver for our 40-pin TTL displays. In particular, we suggest it for use with single board computers (or desktop/laptops!) with DVI/HDMI output like the Raspberry Pi or BeagleBone Black. You can power the driver over USB and then feed it video via the HDMI port. It's a very small board so great for tucking into an enclosure. It can drive our 4.3", 5.0" or 7.0" displays but we really only recommend the 5" or 7" 800x480 as some computers do not like the low resolution of the 4.3" and the TFP401 does not contain a video scaler, it will not resize/shrink video!
We ship this board with an 800x480 resolution EDID so it will be auto-detected at that resolution. For advanced users, the EDID can be reprogrammed using our example Arduino code. Or, for computers that use linux, you can always just force the resolution to whatever display you have connected.
This is just a decoder breakout, a display is not included! We recommend either the 800x480 5" with touch or 7" with touch. Please check out the detailed tutorial on adjusting the backlight brightness. We also have information on how to tweak the EDID if you want to use other display resolutions. If you need a little more distance between the driver and display, check out the 40-pin FPC extension board.
