This is our 'workhorse' display driver board. It has multiple inputs and works well with both TTL and LVDS screens. It does not, however, have an audio output.
This driver has a scaler built in. That means you can use it to drive an 800x480 display but set the computer to output 1280x800 and it will scale the display down. However, the image will be stretched out (distorted) if the aspect ratio of the scaler doesn't match up. For example, if you have an 800x480 display, the aspect ratio is 1.66 so 1280x720 would look stretched out (1.77 ratio) but 1280x768 would probably look OK (1.66 ratio)
The VGA, Power and A/V inputs, the white JST ports are good alternatives to the main inputs if you don't want bulky cables coming out the sides of your driver board.
All the white JST connectors are JST-XH type, 2.5mm pitch.
Power Input: In theory, the board datasheet says 5-24V but we found that 9-12V DC works best. There's a switching regulator so current draw will be lower when using higher voltages, and vice versa.
Datasheet with diagrams
On some of the driver boards, there is an inverting transistor package that is now placed as a resistor (and signal inverted in software). While it's not the most aesthetic solution, the design is fine and these boards are tested and work!
Each driver board comes with a few menues of customizable settings. We go through each below, with some helpful pictures, to show you what you're able to easily control!
The keypad buttons help you navigate the display menus and sub-menus.
As shown in the picture above:
- key is DOWN
+ key is UP
MENU key is SELECT (brings you to the next menu or option)
AUTO key is BACK
When you first start up, you can use the Auto/Back key to select the input source!
