The TFP401 HDMI/DVI Decoder is a small board that serves a useful purpose. Now you can easily add a 40-pin TTL/TTF display, via HDMI/DVI video, to a Raspberry Pi project.
What makes this board a little more unusual, other than its diminutive size, is the addition of an AR1100 USB resistive touchscreen driver. You can power the board over USB and send the signal out to a small 40-pin TFT display.
If you need to connect an 800 × 400 LCD display to your Raspberry Pi, and you want a simple way to drive it, and add touchscreen capabilities, this is the perfect solution.
Adafruit also designed a version of this board without the included touchscreen electronics. It will save you a couple of bucks, but you’ll lose the beauty and functionality of integrating a touchscreen.
They rate the board 9 out of 10, saying “A simple way to add a high-definition screen to Raspberry Pi.”

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
