A TFT panel connected to a Raspberry Pi without the use of an HDMI decoder? What is this sorcery??? It's the DPI Kippah from Adafruit! This HAT-like* board snaps onto a Raspberry Pi B+, A+, Pi 2, Pi 3 or Zero and with a little software configuration, allows you to have what normally would go out the HDMI port come up on a nice little flat screen. * Its not technically a HAT due to the lack of an on-board EEPROM, but its the same shape as a Pi HAT and its a covering of sorts, so we call it a kippah
The other catch is that this display replaces the HDMI/NTSC output, so you can't have the DPI HAT and HDMI working at once, nor can you 'flip' between the two. Also, there's no PWM's available so you can't have precision backlight control unless you somehow rig up an external PWM generator with a 555 or something. Finally, we did test this setup with a straight-up Raspbian and after the software installs, it works great. However, we don't guarantee it will work with any other Raspberry Pi operating system or setup.
