This 7.0 - inch TFT screen is a great choice when you need ample space for graphics or a user interface. It has a high - resolution of 800x480 pixels, an LED backlight, and a resistive touchscreen overlay. Commonly seen in consumer electronics like miniature TVs, GPS devices, handheld games, and car displays. The 40 - pin connector offers 24 - bit color capability with 8 red, 8 green, and 8 blue parallel pins. This version comes with a 4 - wire resistive touchscreen, similar to PID 2353 but a bit pricier due to the touch panel. It's a 'raw pixel - dot - clock' display without an SPI/parallel type controller or RAM. It needs to be constantly refreshed at 60Hz with a pixel clock, V sync, H sync, etc. High - end processors like those in the BeagleBone can support it natively, but it's rare for small microcontrollers. The backlight requires a 125 - 150mA constant - current mode boost converter up to 9V. We recommend pairing it with the Adafruit RA8875 driver board in our store, which can handle the video RAM and timing requirements. It's the best way to connect this display to most microcontrollers including Arduino. For HDMI or DVI output control, check out our TFP401 driver board. Advanced electronics enthusiasts can try direct wiring, but we have no support or tutorials for that.
Using this 7.0 - inch TFT display is a breeze. First, pair it with the Adafruit RA8875 driver board if you're using a microcontroller like Arduino. This will handle all the complex video RAM and timing stuff in the background. If you want to control it from an HDMI or DVI output, use our TFP401 driver board. When it comes to power, remember the backlight needs a 125 - 150mA constant - current mode boost converter that can go up to 9V. As for maintenance, keep it in a clean and dry place. Avoid touching the screen with sharp objects to prevent scratches on the resistive touchscreen. And don't try to directly wire it to your processor unless you're an advanced electronics enthusiast, as we don't offer support for that kind of setup.
